No, that's improper flammable gas management. Constant igniters need to be close enough to all cells to be effective in preventing the creation of a confined space bomb.

Maybe. GP's comment about LFP is highly strange to me, as this type of batteries already passes the puncture test.

Li-poly, which are in just about every electronic device, on the other hand...

Most LFP cells deflagrate under puncture releasing invisible copious hydrogen gas that may or may not ignite.

LiPo packs are rarely used in consumer electronics, they're mostly used in toys and drones as individual pouch packs. NMC is the most common battery chemistry used in consumer electronics. You might be confused because NMC is available in packaging including prismatic, pouch, and cylindrical configurations.

An so, soon you'll be able to put a hydrogen cell into the system ...
