I mean "norepo", "optionalrepo" are probably already used in external
extensions. The idea to use one "needrepo" to rule them all is good but:

- If we remove "norepo" and "optionalrepo", we may break something.
- If we keep them, new developers may get confused which one to use.

Looking forward to it!

Guess I may want to modify "Reply All" to make it "To" the list instead
of "CC".
