Sure, but that was like internet-centuries ago, right?  I'm not necessarily
advocating a relaxation of the b/c policy on the ui, but instead a
strengthening of the b/c policy for the API.

Oh, I totally get that.  Despite a stable API and strong recommendations to
use it when extending Mailman, almost everyone still uses the command line
programs.  Hopefully that will re-balance in MM3 with a stable REST API and a
better separation of core logic and cli.  I certainly don't expect it to go
away though.  #shell-hackers > #python-hackers.
