Windows hibernation is about as broken as linux hibernation, i.e. they both mostly work most of the time, but there is good reason both hide them away by default (if you can really say linux hides anything, with these things being decided by distros and not kernel devs). It is naive to say windows has “solved” hibernation. Either you don’t use it much or have very basic hardware and software needs.

Edit: as a side note, neither iOS nor android devices use anything similar to hibernate, so I am a bit lost with what you mean by arm causing hibernation implementation pressure.
