I want to say something much stronger than this, though -- I want to
require that UAs not close the action namespace. On the other hand,
there is reason to allow the UA to potentially block dispatch of
particular intent types for reasons that aren't obvious now. So I'm
trying to be careful in saying that.

I do think this is testable: create a random string, use it as the
intent action, and see if the UA dispatches on it. If it does, that is
really strong evidence that this spec requirement is met.

Suggestions of a better way to say this, or disagreements about
whether that's the right thing to say, are welcome. :-)
