It seems that there is general requirement for URI matching. URIs are not
only used in subjectAltName, but are used in X.500 in general, i.e., for
RFID support. Defining uniformResourceIdentifier as just an IA5String may
also be a simplification.

Somewhat paraphrasing a question that I think was asked at the app area open
meeting last week, is it the intention to encourage new protocols/services
that adopt/reference this proposal to favor matching based on URIs where
possible or appropriate?

That's something I'm in favor of, and I think worrying about what users
think they're connecting to is really beside the point; users don't get this
stuff. Our software is supposed to do the right things for them so that they
don't have to.
