To accomplish this, I think Rosters have to be named, or otherwise
identified with a human readable label.  "Roster 17" or "the Roster
containing these 17,000 addresses" won't be a good way to identify a
Roster whose linkage to a MailingList has been broken.

They're things like "the welcome message in the 7 different languages
this list supports".  Each contains a set of LanguageTexts for a
particular message in a specific language.

I might call these "dormant".  For example, dormant lists can be easily
resurrected (I'm thinking Python's SIGs as an example).

Such as?  Can you provide more detail in what you're thinking here?

I think we have at least a good start on that.  I'll try to find some
time to describe what we've got.
