Better to specify how browsers should behave (especially if it's how most of them will behave), and let the stragglers pick up the slack in their own time under consumer pressure.

I'd question, based on the following statements, whether your memory
of Acid3 is correct:
"Controversially, [Acid3] includes several elements from the CSS2
recommendation that were later removed in CSS2.1 but reintroduced in
W3C CSS3 working drafts that have not made it to candidate
"The following standards are tested by Acid3: [...]
* SMIL 2.1 (subtests 75-76) [...]"
SMIL 2.1 became a W3C Recommendation in December 2005.
So, there is some precedent for the W3C to publish specs/tests,
expecting browser vendors to catch up with them further down the line.
