I think these are both worthy ideas, though perhaps they can be merged.

I think we should explore this, but it's going to be tricky.

As reinvented wheels are often hexagonal, I think if we are going to
do this we should adopt draft-zyp-json-schema-04 as a base document
for further work.  This has now expired, but is still available at
<https://raw.github.com/fge/json-schema-validator/master/misc/specs/draft-zyp-json-schema-04.txt>.

I note that this draft proposes "application/schema+json" as the media
type for JSON schemas.  That leads me to believe we should make "*/*+json"
official, parallel to "*/*+xml" per RFC 3023.  I'll post on that separately.

        Is it not written, "That which is written, is written"?
