That is overly complicated. If you have never seen a spark when you plug your charger into your battery, then your charger and battery have up to date designs, they risk nothing. If you do, then post your experience here so other people can learn from how you solve your spark problem.
The problem is that the first spark can destroy the battery, like it did with mine. I was able to replace the jack socket, but most people wouldn't be able to do that. In other cases, it would blow the charge fuse. many people wouldn't be able to deal with that either, since it involves opening the battery and soldering in most acses.

The leaflet which arrived with my battery states I must plug the "D-Power" charger into the mains while switched off, connect to the battery while it's switched off, then turn on 240V to charge. There are no instructions/destructions for what to do if the battery is to be charged while it's switched on, but I haven't noticed any sparks on the rare occasions I've absentmidedly connected the charger to the battery while the charger was switched off and the battery was switched on - if I did, I might be inclined to make a short plug-in extension lead from the battery jack to a no-spark XT90 connector, for the charger's short extension XT90 lead from it's jack, which I'd also have to solder together. But they have been known to fail:

I am sure these things have happened and it's better to err on the side of caution. However, the vast majority of users are blissfully unaware because a) the connectors are better designed and built, the sparks are not noticed and b) the chargers and BMSes are also improved over time. The last time I saw a welded, badly damaged charging port connector on a battery was many (10?) years ago.

It's only a problem with the 5.5mm Jack's.

Maybe if you look to see what happens, you can see. Switch your battery on and the charger off. Check that the charge port is live because it's possible that switching on the battery switches off the charge port. Put the jack in the socket and see if there's a spark. If there is, twist the jack to remove it. Don't just pull it out. Obviously, you can only do it once because the battery will charge the capacitors in the charger as soon as you plug in. That's the problem, so if you try again, the capacitors will already be charged and there won't be a spark.

'Pets caused more fires than batteries or e-bikes last year'
"One UK fire service has attended 10 house fires caused by the family pet in the last year, according to figures from the BBC. Surprisingly, that was more than the number of blazes linked to lithium-ion batteries, electric bikes or scooters in the region."

20yrs ago young daughter had a massive black rabbit called Phoebe, I hated it as whenever it was out it was shitting and pissing everywhere and always ended up behind the tv cabinet chewing cables. I had to patch the power cord (240V) from the old 32inch old skool telly and video more than once, how she never electrocuted herself I'll never now... She also destroyed a few coax cables and a PS2 video cable and dance mat....grrrr...

That rabbit 'disappeared' one day, escaped form it's outside run that I built for it from old wood in garage. We found it approx a yr later running about front garden of the house 100yds down the street, spoke to the lady gardening and she said it just turned up one day in back garden. I let the lady keep it as my daughter got two new ones (Starksy and Hutch that lasted 2 week before they 'dissapeared', fox most likely this time), so she was getting older and gone off the idea of a rabbit... How unfortunate.

China introduces world’s first EV battery safety law requiring fire prevention
China has passed a new electric vehicle (EV) battery safety regulation, becoming the first country to mandate that battery packs must not catch fire or explode, even in the event of internal thermal runaway.

Game changer if it works and is effective

King Canute took a similar approach to stopping the tide coming in.. how did that work out?

Did he Drown
No. He decided to retreat after the cold North Sea water got into his socks, and he was also a bit worried about the crabs biting his toes after someome told him how big they grow in Southampton water. Don't forget that there was no over-fishing in those days and local crabs of more than a foot across the shell with pincers as big as your hands were quite common. There are still some around today:
