He won't do that, because it's not possible.  You cannot freely copy
from a copyleft code base into a non-copyleft code base; you must
indenture the latter.

What we can do is branch the code, and freely copy back-and-forth
between Mailman core and the code we got from the non-copyleft code
base.

The potential costs of that I point out in another message, so don't
reply to this one. :-)
