Ben had, at some point, his hGRRDL idea which, conceptually, meant that some transformation on the DOM tree can be done before processing it through the RDFa route. Ie, the current RDFa spec, the processing part in particular, can be kept unchanged (it was quite a balancing act to get it right back when Mark & co wrote it, I would be pretty much scared to touch it) and all additions could be described as a pre-processor step yielding a DOM tree that would then go through the current RDFa mill. My implementation actually implements this approach (actually, users can add their pre-processing steps if they want) and I could implement a number of things easily this way. My current proof-of-concept implementation of @prefix uses that model, and adding the http: trick could be done exactly the same way... Just my 2 cents...
