From my perspective as a registrar, I'm in complete agreement with Gavin:
arbitrary registry-specific extensions and behaviour variations are hell for us,
and the less of that there is, the better for us.

It would be better, from a registrar's perspective, if we attempted to nail down
this kind of thing as well as possible now, and later, if it turns out that
further statuses are required, the list is revised (and possibly the version
number is bumped up). That allows registrar clients to key their behaviour to
things announced at connection time rather than being riddled with
registry-specific behaviour.

Extensibility is all well and good, but a well-defined set of states and state
transitions that *everybody* agrees upon is vastly more valuable.
