With SPIN there would be
- a library of standard constraint templates that has semantics that can 
be hard-coded into selected tools
- an escape mechanism to fall back to SPARQL if the templates are not 
expressive enough.

We are talking about two *profiles* of SPIN here - the one that only 
consists of pre-defined templates would be equivalent to ShEx in that it 
doesn't even require an understanding of SPARQL and can be represented 
in a syntax that is friendly to human users.
