That just seems vulnerable to things drifting out of sync.  It's also
bizarre to work on a level 2 simultaneously with level 1 when they're
both at the same maturity level.

I don't think that's particularly weird.  The Image Values spec
defines new types of values for a handful of properties.  Shaders is a
pretty unique and large type of value, and can survive being defined
in its own spec.  It would be like having Gradients be their own spec,
which would be perfectly appropriate (it just happened that we had a
good spec with very little else in it that could take it).
