Sure, but nowadays, that boils down to a single SPARQL query, or a 
find . -name '*.ttl' -exec perl -pi 's/rdfstar/rdf/' {} \;
across the file system. ;-)

I think the main question is how far you expect RDF* to proliferate beyond 
the WG participants before you get to CR. If you expect wide uptake from 
now on, then yes, it would be too much to ask users to consider two 
properties as synonyms, or to change data that are in production system 
deployed with customers. Indeed, you wouldn't want that to happen.

But if it is mostly WG members who make systems, who is aware of the 
possible changes, then I don't see why you would be pushing this without a 
clear mandate. This is a group that has to be committed to changing things, 
because a standardisation effort is never a rubber-stamp exercise. Only when 
there is a Recommendation, participants have a legitimate expectation of 
stability. In practice, certain things become de facto standards quicker, 
of course, which is really the problem here.

I don't know what kind of traction you have. I was at the Berlin workshop 
back in the day, and I think it is a very interesting and worthwhile effort, 
but I also know it is hard to get a lot of traction early. I therefore 
don't think it is mostly a technical question, it is mostly a technology 
dissemination question. 

Cheers,

Kjetil
