Heat can accumulate. You just need to operate near the safety cutoff limit and over the battery spec for long enough.
Anyway, there are layers of protection. More the better.

A chip can only detect current that's running through it or a sensor. A breached or shorted cell has a massive overcurrent between two parts of the cell and hence can only be detected by heat

But that's not an error which can be caused by badly written software (i.e. like a Linux kernel).
So there's theoreticly no increased risk with running different "home-brew" OS builds on this phone due to software-related aspects of those builds.
It seems like good redundancy to have thermal cut-off but theoretically a fire would have to be preceded by a massive overcurrent anyway, no?
