I agree, it's not a great situation.

I'm still hesitant to re-open the discussion, because while this is 
important, it's not clear to me that there is really new information here.

I took a look back at the original resolution & discussion around it at 
http://www.w3.org/2009/sparql/meeting/2009-05-06#resolution_3 and it 
doesn't really help refresh my recollection of who the biggest 
supporters of the numbering scheme are, other than remembering we went 
around the room and there was pretty clear consensus for numbering 
/Query as 1.1. I don't recall if we had a particularly long discussion 
about the fact that the new pieces would end up as /Foo 1.0.

Anyway, I'd like to hear if Steve and Paul's concerns are resonating 
with other working group participants. We can slot it in for a few 
minutes on the teleconference, since it's clear that Right Now is the 
time to get this right (if there is such a thing as "right").
