It might be more accurate to say there was more opposition than support
at the time.   There was some support.   Manu might be offering more --
and, more to the point, he's making a new argument that might
potentially be supported by data.   (He's arguing for simplicity to
appeal to potential adopters.  RDF experts are in some cases the worst
people to assess that kind of argument.)

Other than backward compatibility -- which we're breaking on other
places already, can you think of any reason we're using @prefix instead
of SPARQL's PREFIX?
