Certainly OSs like Debian believe they own /boot and that packaged files
go in there.  In general it is easiest to just keep it part of the root
filesystem.  The EFI boot partition on the other hand is shared by all
OSs on the system.  There is rarely a good reason to make a separate
partition for /boot these days.  Encrypted rootfs is one case or root
on LVM, but other than that, not really.
