Yes! Inaccessible components are bad. But I am optimistic that what
Rafael is advocating is slightly better than the alternative. FWIW, I
Iooked at it a year or so ago
(http://wiki.whatwg.org/wiki/Custom_Tags_Analysis#Accessibility), and
distinctly remember the notion of "killing bad patterns by baking
accessibility into components" as a hopeful sight of light at the end
of the currently available tunnel.

If you look at the two alternatives, one (the "is" attribute) asks the
authors to make the right choice. The other asks the component
developers to make the right choice. In the former case, the pool of
people who need to do the right thing is several orders of magnitude
larger than the latter. From there, it takes pure statistics to figure
out which alternative is likely to get better results.
