Steven, from the very beginning of Beta Features we acknowledged their would be Beta Features that were only for experimenting and exploring, that they wouldn't graduate. So this isn't a concern of mine. I think the only way we'll be able to get a good solid review of the controls, both internally and from users is to package it up as a beta feature and let people use the real production site with all the new controls in place. Matt's test instance is great but won't serve the same purpose.

Having a new feature we want to try and test but then decide not graduate is one thing. Nearby for Desktop was a good example of this. But releasing a beta feature we definitely never intend to graduate is just silly and a waste of resources. We want everything to look and feel consistent, hopefully with the nascent mediawiki.ui style as the standard. We mostly definitely do want to graduate new button and form styles to all core forms. It's actually one of the main complaints from the community early on in the process, that we were doing things in a piecemeal fashion. 

Before we push out a production beta feature, we still have work we can and should do to clean up button and form styles in mediawiki.ui, which we can use Labs for. For instance, the crappy typography in the buttons which is off-specification, the lack of appropriate padding for buttons, the messy state of the wikitext edit form with mw.ui controls, the inconsistent style of placeholders, and lots more.
