Is there a use case that isn't covered by DOMImplementation.hasFeature()?

For example, is there a UA that would render MathML, and support scripting,
but not respond correctly to .hasFeature("org.w3c.dom.mathml", null); ?

Well, there is XBL, which is a viable method of using a script to add
support for a foreign namespace.  But I guess that's not what you're asking.

And I guess in the case of conditionally binding an element with XBL, you'd
use scripting to do the binding instead of CSS.
