An open question on fan curves

Environment: I am currently playing with a pid control function for my gpu fan, that is instead of saying "map temp x to fanspeed y"(fan curve) say "set fan to speed needed for temp z"(pid control)

Question: is there a reason pid type control is never a thermal option? Or put another way, is there something about the desired thermal characteristics of a computer that make pid control undesirable?

As a final thought, I have halfway convinced myself that in a predictable thermal system a map would match a set of pid parameters anyway.
