    I'm not sure what the difference between "contribute new changes" and
    "install new versions" is.

In the gnus directory, the Gnus developers occasionally copy in new
versions of the files.  (They look first for changes on our side that
ought not to be lost.)  But they should not do this for files
outside the gnus directory.

    Do you mean that a patch from a gnus maintainer would have to be
    posted to the mailing list to be put into emacs (unlike Gnus
    changes)?

I mean they should treat these files the same way they treat all the
other Lisp files that are not part of Gnus.  That does not mean ALL
changes have to be discussed.  They can install local uncontroversial
bug fixes without discussion, just as any of us would.  However,
beyond that, they ought to post on this list.
