You're ignoring that new style virtuals can have versions; thus
virtual/tr-[arbitrary version <1]
can be 'almost full 1 support'.

Yes, mildly hackish, but it address that concern.

As for "whatever I build against, I hard RDEP on", as said elsewhere, 
need a way to specify that an rdep is 'binding', non changable.
