I like the idea.  I am thinking we could (at excuse time) reject
packages with a breaks/conflicts on priority:optional or "higher"
(unless the package is priority:extra).  This would mean we don't have
to "maintain" the faux-package and Britney would just "DTRT" on her own.
  Though it is probably not a flawless solution unless we at least also
check the dependencies have the right priority at excuse time as well[1].

[1] Else out-of-date priorities could cause the "effective" set of
packages in {required,imported,standard} to break co-installability.
