Note that there are going to be a lot of servers in exactly that situation
when we release the standard, since we didn't rename LIST OVERVIEW.FMT to
something new.

I guess the root question is whether there's a need to place a restriction
on what commands a server implements other than the standard "if you're
not following some document intended for standards publication, the
command should start with X".

If clients start running random commands without LIST EXTENSIONS
information to support their efforts, they may or may not get what they
expect, and I think that's fine.
