I cannot either understand why the first went into the 787. Give it a few years, and I think unless the Chinese dumps a whole lot more crap on the market, a really great solution will present itself.
early Shorai batteries had an internal short problem which has be fixed long ago. battery melted, but didn't go into thermal runaway (explosion) it's hard even with wild abuse to cause a fire with LiFePO4.

I am aware of one such situation with a LifePO lithium and the damage was considerable. It is one reason the 650GS single battery location is not so good in getting to it in an emergency situation
this is another issue that comes up ... LiFePO4 batteries are substantially smaller than OEM. probably making factory anchoring system not useable.

dead short dangers are very real .. lithium batteries discharge at extremely high rates ... easily generating heat equal to Arc welding. we all have heard about welding setting off fires.

then factor in folks that relocate batteries to completely different locations. don't lose your bike to a fire caused by dead short ... which are NOT the battery mfg's fault.

batteries with cable leads have the highest risk of dead shorts. due to lack of hard mounts. black electrical tape is not enough. insulate positive connectors with a piece of rubber hose slit sideways, then tape that down good.

make absolutely sure, battery cannot dead short out!!
