It's of course true that what my track in the CSS WG has strongly
influenced my views on the matter, but no I was not thinking of 2.1.
Most of our specs suffer from the same issue for one good reason:
our tests are super-complicated to write, require deep knowledge
of not only the spec to test but also all other CSS specs because
of potential collisions/interactions. Even for Selectors, a Test
Suite I started myself, that are a spec a bit more isolated than the
others inside CSS, it took us years to complete it.

Testing a new device API with one new DOM interface having two methods
and two attributes is one thing. Testing flexbox or animations or
filters is going to be another story...

Absolutely.
