Arguably.  Debates like that should take place in the right place, though.

It's not about committee experience (most modern Web spec development isn't
done by committee).  It's simply that specs can't force browsers to do
anything, and that they long ago stopped pretending that they can.
Browsers will have their policies regarding prefixing, and if you disagree
with them, telling them to change it in strange venues like this is an
empty gesture at best.

You said it was "mandated", so I assume that wherever it is, it's
considered normative.  The right place is presumably on mailing lists, and
other places where cross-vendor discussions take place.

My goal is to keep WebGL implementable. This means that if by 2015 a new

That's fine, but per-API mandates aren't going to help that goal.

If it's controversial, then it belongs there even less.  If vendors
disagree, they're just going to ignore it; if they agree, they'll do it
anyway.  Each individual spec demanding specific un-prefixing policies is
just going to be a bunch of noisy handwaving that everyone will ignore.

That text is also poor practice: it doesn't give a transitional period.  A
more reasonable, real-world policy is to remove the prefix after it's been
present un-prefixed for at least one production cycle, so people have a
chance to test their API selection code with the un-prefixed name, before
their code actually depends on it.  (It also doesn't acknowledge the
existance of production cycles; *immediately* removing an API would imply
remotely removing it from deployed browsers, which surely nobody will ever
