And I'm entirely against. :-)

1) No nesting! Unless we first provide an alternative style sheet
language that is easier to use, we cannot turn CSS into a programming
language. CSS is essential for the semantic Web; reducing CSS usage
without providing an alternative means abandoning the semantic Web.

2) We aren't worth our name as standards organization if we can't make a
standard that is actually implemented. We're not doing designers a favor
by recommending that UAs implement a little bit here and another bit there.

I know we're having a lot of difficulty publishing the snapshot of
interoperable CSS that we promised two years ago, but I'm not fatalist
enough to declare that therefore lack of interoperability is the new
