The point is it shouldnt have to, it would be able to play it if it was a
more common format, the whole point of having a must implement format is
that it follows the rules of lowest common denominator, thus the minimum
format requirement should be one that is usable in the most cases possible,
thus MP3. Ogg Vorbis should simply be one of the extra recommended formats
since it is not nearly as ubiquitous and requires special libraries in the
majority of cases since its not available as standard in most cases.

By making Ogg Vorbis the MUST implement you are forcing these web clients to
not be allowed to implement audio CAPTCHAs since they cant support Ogg
Vorbis without extra libraries, so even if they do have other codecs
installed they arnt allowed to use them.
