I assume you mean "No" to the second sentence, not the third.

Not at all.  The meaning of the message on-the-wire is independant of
whether the service implements it or not.

Sure, that's an issue, which is why registration (normally via some
form of standardization) is important.  Or alternately, identify the
method with a URI, ala PEP (and maybe Waka, dunno).

Well, that's the gist of a good amount of Roy's dissertation.  Section
5.1.5 doesn't say anything about the interface needing to be standardized
to realize the benefits.

Obviously standardization is responsible for much of the Web's
growth, but AFAICT, it has nothing to do with the technical benefits of
the uniform interface.

It is true that the value of standardization is greater because the
interface is so general (because of reuse), if that's what you mean.
