Support the standard!    The SPARQL query language is a
single spec formed where there were maybe tens of query languages.
Coming together on the standard is, of course, very important,
so that one can write a program once and switch storage technologies
underneath it.

If there are cases when engines give different results from the same  
query on the same graph, then talk to the working group about it.   
Get the crucial bits in as a test case.
