It's a trolley problem, and it's not in Microsoft's locus of control to keep dual boot systems dual booting. So they don't try.
They have never, ever supported anything other than the Microsoft bootloader[s], and if you work around that for instance it's pretty trivial to blow up your data by hibernating Windows and booting into a different partition. Resuming hibernation loads the old MFT onto the modified partition and you pretty much lose everything.

Definitely to be avoided, along with a few other considerations.
But experienced multibooters can usually reboot so quick that they have not had any need for hibernation since forever. It's almost like a valid excuse to not fully reboot a sluggish machine, more so than an energy-saving success. But I don't blame them.
