Isn't that nitpicking a bit? It's part of the feature-set that a browser
would have to implement, part of the books that have to be written,
etc..., right?

Exactly, RDFa makes far fewer demands.

So, since we've written the documentation, and we're willing to write it
in the context of HTML5, what is the *significant* cost to the HTML5 WG?

Just to be clear, I meant "not now" for user-agents' mandated UIs, but
certainly "now" for integrating into the language and letting user-agent
extensions handle them.

I'm only trying to frame the complexity of RDFa to that of another new
feature that was recently added. I wouldn't dream of comparing to CSS,
which is obviously not new.
