I have a sense we don't know enough of the problem space to enforce a (standard) default or a (standard) verbosity level. I'm leaning towards letting implementations handle this.

OK.

There is nothing in the current API that prevents me from doing the above; I should be able to add Hypermedia support to an existing application without any major restructuring.
I have updated the wiki to discuss @Linkable, but more as an extension of @Rel. Maintaining unique global IDs can be a hassle for large applications, so I'm proposing that to be optional.

Yes, sure. Once we settle on a strategy we should add convenience methods to facilitate adding links to responses.
Thanks.
