TMS doesn't mean the same thing as temperature controlled cycling.
Put a battery in a thermal chamber set to 25C...and the case of the battery might be at 25C +- 1C. But real cars do not and can not keep the temperature at a constant 25C. For example, Telsa Model S BMS seems to start cooling to limit temperature at 45C.

My LEAF's battery, even on a summer trip with multiple QCs, has not gotten close to 45C. At best a TMS would only add weight, reduce reliability... about the only good thing about a TMS would be that power draw would be minimal locally. Because it would never turn on.
Yes, I know it is different in Arizona.
