I don't think that the proposed change is "invasive"; it's mainly 

However, you don't consider the impact on other registries of link 
relations; may I remind you of 
That doesn't scale well for additional elements in HTML, or constraints 
in other formats.

First of all, it *does* change the complexity of HTML, until you add 
prose disallowing different meaning on <link> vs <a>. You haven't done 
that yet.

Second, I'm thinking of the complexity of link relation definitions in 
general; not only in HTML. For that, it's important to be clear that the 
semantics of a link relation should not depend on where it appears.
