Do you have any reason to suspect that others aren't being used?  The
default format for anything is likely to be the most commonly-used
one, but I don't think that proves the others are unused.

Even if it were true, it wouldn't be a good justification for
inventing an entirely new machine-readable format, at least not IMHO.
