It would indeed make it more RESTful and clever move there to keep the old  
functionality (which at least I find quite useful) through POST.

I give my vote for the change if and only if we update the HTTP Rendering  
spec to include explicit ABNF grammar for each different use case for the  
Category and Link headers.

For example, a Link header in a PUT /compute/123 MUST have the self=  
parameter specified but MUST NOT have any Link attributes specified. The  
Link title parameter is also a MUST NOT in this case since it refers to  
the title of the target resource.

Maybe we can just break it down into 2 use cases per header, i.e. Link  
header ABNF for requests and Link header ABNF for responses.

The change is good but there are all these little details that could cause  
lots of interoperability problems if we do not specify them very precisely.
