I like this. The design looks like it strikes a nice balance. It doesn't involve supporting multiple path semantics, it provides intuitive results to the use cases in F&R, and it leaves plenty of room for expansion of property path features in extensions or future SPARQL standards. I wonder if there might be some pushback on dropping the {n,m} form, but otherwise I think this is great. I'd support this over the alternatives we've been considering.
