I agree that trying out if an optional argument is accepted or not isn't
a nice solution, even though it works and is probably better than adding
block-stream-2, ..., block-stream-7.
Didn't you say a while ago that adding a command that would return the
JSON schema wouldn't be all that hard? Maybe it's the right time to
implement it for 1.2.
