Right. Or you might have plugin-based fallback you can use if you get
"maybe". Other authors with no plugin-based fallback would go ahead if they
get "maybe".

I agree. In the past I argued for two boolean functions.

Anyway, it's a little late now to change canPlayType more than we just did.
There is already deployed content checking for "probably"/"maybe".

"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
