Point where?

I didn't mean new spec for the algorithm, just for how it is used with the OAuth authentication scheme.

There is no need to publish a new spec for a new MAC algorithm. MAC algorithms typically go through certification (e.g., NIST) and have detailed specs, including test vectors for interoperability.

For OAuth, if you want to explicitly support a new MAC algorithm you will not need to change the transport and you just have to point to the particular spec that defines the MAC algorithm.

People are going to end up needing to write new code every time they
want to add a new MAC-based algorithm.
Cheers,
