Hmm, this is not clear to me. Are you intending to remove the name=
mount option entirely, or just intend to remove that you can change it
in remounts?

systemd uses name=systemd to get its own private cgroup tree, that has
no controller bound, hence we kinda need this option. Or are you
suggesting there was an other way to get a private cgroup tree that
systemd can use for grouping and labelling things?
