Thermal runaway in lithium ion batteries starts at 100C and is a significant danger at 60C.
Maybe learn more about subjects before you come up with all these opinions on how things should be done.

For example, even DEC can be made safe to 175C at 3 bar[1]. 3 bar isn't a lot for a liquid filled metal can.

Obviously they can still suffer thermal runaway, but it happens at much higher temperatures.
