Yes.  I know.

At least initially you may have to have different MD files which differ in
the set of target patterns they include.  This isn't rocket science to do.

I disagree.  This is a fundamental design issue -- if it doesn't work or
proves to be exceedingly difficult to implement, then this whole direction
is a non-starter.  I don't think that will happen, but the proof will be
in our ability to code this.
