I think the general policy is to code for the latest official Emacs.
Backwards compatibility is nice but not imperative.  This is just my
understanding, though.

I think supporting Emacs 20 is, realistically speaking, not desirable
because of the many useful functions in Emacs 21 (like puthash) we'd
have to emulate.  Yes, it can be done in every source file, but why
not just have a gnus-c20.el or something like that to provide the
compatibility layer to Emacs 20?  Moreover, is there a sizeable Emacs
20 user base we want to support rather than force into upgrading?

I don't know the answers to the last question :)  It seems to me from
discussions here and on emacs-devel, however, that the answer is "no."
