I don't want to be a killjoy, but why do so many "REST frameworks" focus so much on the transport (HTTP) and not so much / or at all on tools to create and manage hypermedia representations (links, actions, domain objects)?
Keep it up ;)
(Arguments and counterexamples welcome, I've been looking for them for years).
One example, that you find on HNs frontpage right now, is Solid ( https://news.ycombinator.com/item?id=18100895 ). Another example is Google's use of JSON-LD for meta data descriptions in HTML pages. And there is Mastodon, making use of vocabularies like ActivityPub.
The best example though, is HTML and your Browser of choice.
