So, my original question is answered as "yes, you can merge in changes

Publish out somewhere would be useful, I guess. This is a problem I
have found in a few other projects. I can see even a modifier for "hg

Could be implemented as a command line command using "revsets"?.
Propose a new revset to mercurial devels?
