Yes, I think you hit an inside-the-park home run with pqm.

I.e., we have some running to do to make it real (a feature here or
there, etc.) but it scores a major point.  I didn't really appreciate
that until I thought through both (a) why asuffield is using a
pqm-like merge thing in Bug Goo and (b) how to actually deploy for GCC
mainline.

The PQM idea is simple enough (reimplementable enough) that I doubt
any current implementation will be recognizable as the ancestor of
what eventually we bundle with tla.  But you demonstrated this
important idea and gave us a nice handy name for it.
