Including in this specification is no more or less likely, as noted already.

Each of the algorithms' specification is entirely independent, from the point
of view of our REC track requirements.

That is, you can implement this spec with only support for SHA-1 *and* be fully
spec compliant.

Separate specifications encourage separate discussion about the merits of
individual algorithms, including recognizing the fact that UA acceptance is
independent.
