The current proposal for this is probably:
(though there was a bit of discussion following this).  It takes the
form of testing for property:value pairs rather than just
properties, but is otherwise somewhat similar to what you propose.

(That proposal doesn't contain an option for testing
lack-of-support, though.  This might be nice in the long run, but it
wouldn't be useful for quite a while since current implementations
don't support @supports.)

Beware this is just a proposal -- far from standard.
