Which browser ships matchesSelector unprefixed?
Neither Chrome, Firefox, nor Safari ship matchesSelector unprefixed.

That’s just broken code.  One cannot speculatively rely on unprefixed DOM functions until they’re actually spec’ed and shiped.
I have no sympathy or patience to maintain the backward compatibility with the code that has never worked.

Furthermore, the existing code will continue to work with the prefixed versions since we’re not suggesting to drop the prefixed versions.
