Yes, it would be a testsuite that is approved by the WG to cover a
sufficiently wide range of activity.  It doesn't necessarily have to
plumb every single edge-case, though, hell, early test-cases might
help with that sort of interop convergence.

It's basically Maciej's suggestion, just with some rigor applied to it.

[snip stuff about incentives]

Yup, that's an excellent summary.

I'm not sure we can do too much better either. :/ We want to let
authors experiment with things in as realistic an environment as
possible, but we don't want them to bake prefixes into the public web.
 We want to encourage unprefixing fast, but we don't want vendors to
fast-track their shit without getting adequate review.

These are mutually contradictory.  History shows that we've been too
far out on the "late unprefixing" side of the second incentive axis.
We can pull it back, or we can somehow fix the first incentive axis so
that our bias on the second doesn't hurt us so bad.

Tantek's proposal should help in the second axis.
