Significantly smaller, but not necessarily significantly more capable.

Staying with the jQuery comparison, there are TONS of plugins that solve
the same problem. Some in much better ways than others. There's a large
potential for problems when the learning curve for the basics is low.
There's an even larger problem when developers start blogging about their
recent discovery (which no doubt will lack any form of accessibility) and
other developers start learning from there.

I'd say some do, and an extremely minuscule amount actually use ARIA. I'm
not convinced that even the top 10% of developers writing plugins are
always thinking about accessibility.

Accessibility is hard. I can speak personally about how difficult it is to
design widgets for jQuery UI so that absolutely no choice is left to our
users about how accessibility works. Developers will find ways to bend
features to their will; if they can get something to work the way they
want, they'll do it, regardless of whether it breaks accessibility.
