I'm not convinced that having the ability to register link relations handlers would actually work (but I'd be happy to see examples). If your point is that the number of innovations that ought to require a new URI scheme is small, then I agree. If you think that that makes the case against web+ then I think you have a point.

We're talking about a HTML spec feature that is very controversial, as 
was the chair's decision to keep it.

It's up to the WG to decide what's in and what's not. The WG (through 
Philippe) has asked for feedback over here, and there was feedback.

At this point, this feedback should be forwarded to the WG.

Asking to talk to implementers sounds like moving goal posts.
