[arch-general] Standard group for "hardware user"?

I run mdev instead of systemd-udev and was just alerted to the deprecation of all the groups I'd been using. Looking at the filesystem package, it seems that most of them are still present, but I presume they'll go away eventually. What, then, would be the best group for me to use for "a user who is allowed to do things with hardware"? That is, a combination of audio, video, disk, optical, and uucp (which, strangely, is not deprecated). I'm considering "wheel" but that doesn't feel right. And I really don't want to add a new group, I feel like this notion ought to be part of the base install, even though systemd appears to have reworked how Unix device access is controlled. Thanks in advance, Neale
