While revisiting the ABNF, should "fp-type" be made into 'token' instead
of an explicit list ( "sha1" / "sha256" )? Rather than dealing with the
minimal set of "must-implements" in the grammar, define it in the text for
processing rules. This is similar to the conversation that happened for
the STS grammar rules.

I'm just wondering how legacy parsers would be expected to handle future
versions with say, SHA-3. Defining it as a token would at least allow it
to be syntactically valid and parsed, even if fingerprints of that type
are not understood/supported.
