In the event that what I wrote was ambiguous I just want to clarify what I was attempting to say.

Installs of brlapi and brltty packaged by fedora (as early as F27) resulted in the creation of the
brlapi group.  It did not add any users to that group.  I don't have the F27 rpm to examine.
However, the group creation was most likely done by a post installation script the packager
included in the rpm.

Yes -- that is what how I understood the situation.   The brltty devs  maintain Debian and
RedHat packages with different post-install while creating groups with systemd should
work across distros (but the step to move the creation so systemd is easily overlooked, and
may not be noticed for a while since most installs will be upgrades rather than fresh installs).


Just like, for example wireshark, it is up to someone with admin/root privileges to add users
to a given group.

FWIW, the "groups" command can be used to list the current groups of a user's current shell
environment.

For many users, the need to create and join groups falls in the category of unknown
unknowns.
