The usual X way of doing things is you tell the server the highest
version you're able to use, and it tells you the highest version that
both you and it support. This seems sensible to me: the only time I can
imagine it being useful to ask for "no, really, what's the *best* you
can do?" is if you're just going to display the answer to a human. What
else can you do with it?
