No, it's not a question of distros supporting themselves like this.  For
better or worse, people expect to be able to install many OSs on their
drive and have any grub be able to boot any of them.

One such use case I've seen is hardware testing: someone will install
all the operating systems they care about on a drive, then plug it in to
the machine with the hardware and try all of them in sequence.  And of
course there're always hobbyists who just think it's fun to do things
like that - they file bugs too :)

In any case, it's not a little bit of time we're talking about here -
even though RHEL 6 is only guaranteed into 2024 right now, RHEL 8 is
slated to be here until at least 2031.  (Source:
