For me, I don't really care that much how things are specified as long 
as there are test cases for interoperability and the specification is 
reasonably rigorous. I believe that the argument that the language of a 
specification is crucial to its adoption is somewhat silly. I don't 
think that XML caught on with enterprise developers because the idea of 
the infoset was something that resonated with them. (There are many 
other forces that affect the adoption of a specification, such as 
educational materials and working code, but also many practical ones 
such as adoption by Big Players.)

Anyways, as I've expressed elsewhere I think removing the recommendation 
that POST to a graph be append is a mistake.

Also, I couldn't support this version of the specification because of 
this removal:

"""
GSHP defines how to construct URIs for access to graphs in SPARQL 
datasets, with a graphstore+"?graph="+graphlabel construct. Perhaps this 
is better done in the SPARQL Service Description, instead, with a 
predicate relating the dataset to a URI prefix string, not necessarily 
graphstore+"?graph=".)
"""

...that makes the specification largely useless to me.
