Why? "Not at all" is precisely the correct action for a grub2-based
distribution in this case.

I think we should do grub2-mkconfig for such installs, though it's a bit
tricky to refactor anaconda's bootloader install code to do so. I might
have a shot at it if I get a spare minute, though.

But yes, aside from not generating a grub2.cfg for you, this is
precisely the right thing to do. If you don't want Fedora to own the
MBR, then you should not install a bootloader during installation. You
should install no bootloader, and then use grub2 configfile inclusion to
boot Fedora. See
https://www.gnu.org/software/grub/manual/html_node/Multi_002dboot-manual-config.html .

What is your 'other Linux installation'? It's not like we can do
anything if you don't even say that. (But we don't really do anything
special for multi-boot configuration; we let grub do it, via os-prober.
If it didn't find your other installers, it sounds like there's a bug in
grub.)
