I would prefer a document that describe SCRAM as a GSS-API mechanism.

Such a mechanism would be usable within SASL via GS2.  It would also be
useful outside of the SASL framework.

For SASL implementers, in a SCRAM-as-GSSAPI-mechanism document, there
could be a section that describes how to implement it as a SASL
mechanism without having to understand GSS-API or GS2.
