We don't require that the client be Postorius or Hyperkitty though.
While in one sense we're not responsible for what third party clients
do *at all*, in another I don't think we should make it hard for
them.

It's also possible that a third party (hello, Systers!) might have
modified versions of the code, and not realize that their "don't fix
it 'cause it ain't broken" core isn't compatible with their
up-to-the-minute Postorius that they pulled to get Abhilash's security
patch.

I don't think that's the question.  The question is, "what can we do
to make things easier for developers both in the Mailman project and out?"

We don't.  Only the current version.  The problem is that "version" is
a potentially large set.  That *is* *our* fault (looking straight at
Barry with one forearm on the emergency exit crashbar ;-).
