Put me down for a strong "bad idea" vote.

At a stroke this would mean that all currently published RDF will be 
using deprecated terms.

For the "transition" then all tools would need to support both sets of 
URIs and provide some form of interoperation across them. All existing 
SPARQL queries that use rdf/rdfs terms would fail on new data, all new 
SPARQL queries would fail on old data. So publishers would have to start 
providing duplicate statements using both URIs, query writers would need 
to write all their queries as unions to handle both worlds.

I put scare quotes round "transistion" because it is not obvious when 
enough of the RDF world might have been republished using the new URIs 
to allow tools providers and query writers to safely drop the deprecated 
versions. So the transition period would likely never end.

Improvements to usage notes and labelling are possible with no change in 
URI so the only presented argument in favour is that the namespace will 
be slightly easier to remember. Given, as noted in the Against case, the 
vast majority of people don't remember URI's anyway (relying on tools, 
or cut/paste) that seems like a trivial benefit.
