At this point I do not see shaders blocking the standardization process of the whole spec. Should people still be concerned about the implementation status of shaders later in the process, we can put shaders on the risk list before going to CR. It may go into the next level of Filter Effects at this point.

My objection in the CSS WG meeting was based on the 10 seconds I had
to consider an agenda item that was raised at the last minute
(during the meeting), and was not carefully thought out.

I think the features that you're proposing to add rope in a large
new area of functionality that adds a lot of complexity to the Web
platform (pulling in additional file formats that define shaders).
I don't think there's consensus that the value of this functionality
matches the complexity it adds.

(Note that consensus requires not only lack of objection, it also
requires wide support.)

That said, I've only had a few minutes to think through *this*
response so I might say something else after longer consideration.

Discussions like this are the reason I would prefer to see the CSS
working group operate using asynchronous decision making, like many
other W3C working groups do.
