Since you seem to find this so very important I have now added these two 
test cases to the suite. I still don't agree they are important, but I 
don't think this is worth spending any more time on. I have notified the 
other implementers about the new test(s) and hope they can re-run their 
tests.

I have just made the use of VALUES in general ill-formed in 
SHACL-SPARQL, making your submitted test cases outdated. I had never 
rejected them, see my other email in this thread.

So both of the examples that you have used to motivate your formal 
objection are now handled.
