Hello,
While the link property is a little funky, it addresses a common problem:
having two (OR MORE) different sets of properties for the same resource.
Having a GETSRC and a GET for the same resource limits you to having two
representations of the resource, the original and the modified (or authored
or whatever you want to call it).  What if you want a third representation
of that resource?  With the link property, you can accomplish that (I
think).

GETSRC should return the same thing that a GET without any properties should
return.  It seems redundant.  Why not just have more than one set of
properties.  GET with blank properties is the same as GETSRC.

Under what conditions did it not work?  Do you mean just never implemented?

The one that calls for different resources to be accessed using different
URI.
The set of source URI for some other URI are different resources.  Since
there can be many more than one source per representation, the notion of
creating a new method to avoid one indirection is just wrong.
