People argue that, with REST, versioning should be done in headers and not the url. Maybe that?

Nooe, HATEOAS is about links. The official-sounding thing that this would violate is the "server should be able to organize its own namespace."

That said, I don't think this actually mandates any URLs. I read that part as just a suggestion for how it could be done.

[sopooneo]

Does that mean it should be possible to just have the link be "subscription"?

[steveklabnik]

It means that the spec shouldn't specify URIs, and instead publish link relations.

(I'm not saying that I think it should be that way, just elaborating.)
