If /etc/udev/rules.d/70-uaccess.rules would be applied on top of
/usr/lib/udev/rules.d/70-uaccess.rules , that would have been great. As
one can try to revese the undesired rule and still incorporate all
upgrades. But cancelling all the rules is a no go for me as I don't want
to be running an almost unique setup just because udev/systemd/loginctl
didn't think of group permissions.

If systemd developers thought of supporting ACLs based on GIDs at least,
this would have been a no issue.
