Then it probably needs to include a louder hooter and brilliant flashing
lights to serve the same purpose, if more slowly than a purpose designed
dissipator.

That includes 99% of battery users who wouldn't know what to do it they
noticed the warnings or wouldn't be able to do it anyway.

A voice message could be pretty explicit. All the message needs to say
is to move the battery outside to where it can't do much damage if it
bursts into flames. EV car batteries are big enough that that's quite a
way, but cars are designed to move appreciable distances.
It's not really a very good selling point. "Oh, by the way, this model
has the latest upgrade and tells you when it is going to explode, so you
can get out of the way".
You don't seem to have been paying attention. If you deal with the warning by discharging the battery, and making it safe, it won't explode.
No stored energy means no dramatic heating, no breaking of the seals that protect the contents of the battery from atmospheric oxygen, and no explosion or fire.
Yo do have to get rid of the battery and presumably replace it, but that was implicit in the original purchase. They aren't sold on the basis that they are going to last forever.,
