There seemed to be general agreement on the call that option A was the
least bad.  Here's some opening suggestions for names:

1. reset (already suggested by you, just putting it here for organization)
2. ua-default (suggested by zcorpan)
3. user-agent

I like ua-default.  It's even clearer than "default", and makes it
really obvious to people what it does.  It also seems to be
practically guaranteed to not already be used by authors in any
<custom-ident>s we have.  Its only downside is that it's not
technically correct - when used in an author-level sheet, it causes
the user stylesheet to be applied too - but I don't think that's a
complication that matters.
