Hmm... that use case was provided, and sorting has been added.

I'm sympathetic to that comment and many of your others...

That sort of rhetoric is really not constructive. It would be easier
to address your substantive concerns if you left that sort of thing
out. The people in the SPARQL Working Group are real people
with their names all over public mailing list archives and meeting
records. Different WG members have different motivations, some
of which I agree with more than others.

You seem to have a lot of experience relevant to the choice
of SPARQL features and requirements. I'm interested to continue
that discussion.
