Not at all.

If it _were_ like that, it wouldn't break. ">" follows symlinks and
would be fine even with the read-only file perms for root.

If one were forced to use "grub2-mkconfig > /etc/grub2.cfg" or an editor
to insert the stdout of grub2-mkconfig, the symlink would work.

The symlink target is read-only as another reminder that one should
not edit it with an editor but only via the fragments in /etc/grub.d/
