Sure, I have a regex matching my company custom naming scheme, only
different line:
NAME_REGEX="^[a-z]+\.[a-z]+\$"
if it wasn't user configurable it'd make no sense of exposing it in etc.

Afaik the best solution would be not to rely on user defaults in the
maintaner script or
if it breaks apt/dpkg so easily, make it clear in the default adduser.conf file.

Personally I think udev uses addgroup wrong here, see #328053
