Thinking about this a bit more, it seems to me that it would be good
to have two editions of the HIG. One would describe current best
practices, easily implementable with standard libraries. The other
would describe the target design, and would have links to the
relevant bugzilla bug reports where appropriate.

I suggest this because it's hard to keep a picture of a complete,
coherent design in mind based on a document that does not quite match
it, plus a bunch of scattered bug reports and discussions.

The "current best practices" HIG would be the one we ship with GNOME
as part of the developer docs and try to conform to for 2.0, and the
other would be a sort of "unstable branch" of things the Usability
group wants to see in future GNOME releases.

Another possibility is to have only one edition of the HIG, but with
commentary on possible future changes. But I worry that this would
confuse developers and designers reading the HIG, even though it might
be more convenient for the HIG team.
