This is not feasible at least for some legacy cases, like image MIME
types.  It's a good strategy to try for new cases, though.  If it
could be specced for video and audio, maybe we could get everyone to
converge sooner rather than later.

This is totally incompatible with the compelling interoperability and
security benefits of all browsers using the exact same sniffing
algorithm.
