Sounds like a useful sanity-check-point; it should help us notice early
anything that some of us think we have consensus on and others might be
surprised by - or surprised it's gone forward, given the objections they
raised earlier; or that they'd simply not even heard about.

Our existing process's first point has been feature-freeze and that's
when we've got API change review scheduled for; to what extent do folk
think it may be worth starting the API change review earlier, for
example at this new Structure & Platform milestone ?  Might it make
sense to have an initial "overall, don't fuss about details" API change
review in June, ready for this milestone, as a precursor to the full API
change review process, whether that be following S&P or after FF ?

We clearly also need to think about how to do API reviews (not change,
but the actual API as a whole), particularly for things that have
changed or been added, but possibly also for other things in case review
reveals they perhaps *should* change.  I don't pretend to know what
process makes sense for that.  Any suggestions ?
