What is the purpose of the symlink and its shorter path then?

Yes, that would be a wise decision. Especially when it's known that
grub2-mkconfig cannot handle the symlink and ignores the read-only
mode of the file that is pointed at.

On the contrary, Emacs is not so stupid and can handle the old GRUB 1
/etc/grub.conf link, and it can handle /etc/grub2.cfg, too, just that the
link target is not writable and one is expected to no edit the file with
an editor.
