You can’t generally install Linux onto most (any?) existing phones that were not specifically made for it like the Pinephone, so I don’t know that it is helpful for extending the life of many devices.
I am not aware of any phones that don’t already support running Linux (Pinephone, Librem, and maybe one or two others) that can use Postmarket OS. I’d be both impressed and shocked if that has materially changed. Also, I have actually tried out Postmarket OS and it was not ready for use as a daily driver. That doesn’t mean people shouldn’t give it a try though, as it won’t ever get there if technically minded people don’t use it and feed helpful feedback.

Postmarket OS is explicitly for that
