Hi John,

I suspect you're asking a lot of questions here to the TAG, rather
than specifically to myself, so forgive me for just responding to
those questions that I feel I'm in a position to respond to.

No, you were correct to use a new URI scheme.

Just because new URI schemes are more often than not a bad idea,
doesn't mean one should standardize a way to replace URI-scheme
functionality elsewhere in the syntax of a URI.

IMO, the advice you've been given to avoid new URI schemes should have
been rephrased to make it clearer where the problem was.  The advice
should have been to try and solve the problems that XRIs are intended
to solve using http URIs (without additional license ala HXRIs).

Absolutely.  The bar is pretty high over on uri-review, where we
regularly have to educate folks about the value of reusing existing
schemes such as http.

Yes.
