The syntax is very strange.

The Link: header has been a part of the HTTP spec since forever. The following example from the HTTP/1.1 spec [1] should look familiar:

    Link: <http://www.cern.ch/TheBook/chapter2>; rel="Previous"
We should be applauding Google for supporting standard headers instead of making up new ones. The Link: header is even mentioned in the HTTP 1.0 spec [2] and, as mentioned in the OP, there's even an RFC acting as a registry for the various Link relation types [3].

Though I don't always agree with standards, I hope you'd agree that it really does make sense in this case...
