IIRC some browsers using system media frameworks don't know what codecs they
support, so they still need to be able to answer "maybe" when codecs are
provided; you still need a three-valued result.

I still think it would confuse authors if you return true for canPlayType(T)
and false for canPlayType(U) where U is a subset of T.

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
