For Debian, there is some information in the /usr/share/doc/base-passwd/
directory.

Yes, even the base-passwd maintainers who keep the users and groups with
ID < 100 in sync across Debian installations have sometimes no clue what
a specific group is or was good for. Here is what they say about the
'bin' and 'sys' groups:
