[html5] A <ui> Tag?

For the record, I'm in favor of something like a <ui> element, I just
have no need for it :)
I tend to think of the elements of HTML5 in two camps: content (<p>,
<ul>, <h#>) and chrome (<nav>, <header>).
The content side of the equation has generic, non-semantic elements
(<span> and <div>) that can be used for any styling purpose.
It doesn't seem as if the chrome side has a generic, non-semantic
element for using the same way. That's where I think your <ui>
suggestion fits in: an open use element that indicates to any agent
that the stuff inside isn't part of the content.
Where I think we disagree is that the <ui> element should affect the
baseline actions of the content within. A <form> within a <ui> should
still submit as a page refresh unless rerouted by JS.
You are probably right that it's too late in the game to have
something like this added now, but it certainly isn't a bad idea. Keep
it around for HTML6 :)
