Agreed about spinning head.  This is why I suggested at [1] that
anyone intereseted in this start with description of their proposed
design, which would have three benefits:

- after implementation, it would document the intent behind whatever
  we choose to do, hopefully saving people debugging or improving this
  code some head spinning

- it would allow subject matter experts on-list to suggest refinements
  and simplifications

- it would avoid the interested contributor going too far down a blind
  alley in case their initial proposal has a fatal flaw

I also agree with the "theoretically we should be able to make it
work".  As described in [1], I think most of this is work we're going
to have to do eventually, as part of properly supporting multiple
worktrees for a superproject.  But I don't want to set wrong
expectations: this will be hard.

Thanks,
Jonathan
