There does appear to be some of this. I have no idea if that is just an
impression or the truth. Hence my continued following of the thread.

Indeed. I the data-* attributes had some reserved values, then one might
expect people to invest in them on the scale that they have typically made
RDF investments. But then there would be no need to change the attribute
names at all (nor, for that matter, to put much effort into other
attribute names following the design pattern. It just becomes another
approach to namespaces with another centralisation process required). The
question is what would convince the editors of the spec that there is in
fact a use case for RDF in HTML which is what has led to the request to
include RDFa (a form of RDF carefully designed to fit into HTML).
