element.matches() can use the complete profile, actually.  This is why 
the names suck.

I like the 'static' vs 'dynamic' proposal for renaming these things. 
'fast' == 'dynamic' (i.e. your match result set has to respond to DOM 
changes), 'complete' == 'static' (i.e. you match once and are done).

The intended usage is that all the DOM APIs use the 'complete'/'static' 
profile and selector matching for purposes of CSS styling uses the 
'fast'/'dynamic' profile.

See https://dom.spec.whatwg.org/#dom-parentnode-query and 
https://dom.spec.whatwg.org/#dom-parentnode-queryall
