Very much true indeed.  ;)

If that's where we are heading, it's conceptually correct to use
parent-child one-to-many mapping as a starting point (and maybe at
some point extend it to many-to-many) and use terms "derivative"
("child") and "master" ("parent", "source"?).

Well, it is "hacky" only if we are trying to model this (concept 2).
I'd think it is pretty good first step if we are pursuing the concept
1.

Uhm.  It appears to me as if you were conflicting yourself.  Concept
of "derivative work" and native groups at implementation level do not
match.  

If you'd prefer the concept of "derivative work", groups are imo wrong
thing to start with because it is a dead end if you want to reach that
concept.  Having "master" (or "source" or "parent"), as you have done,
is imo right way to start.

Rock on!
