Glenn, That was quite the "friendly" response (not so much)!
If using my Amazon purchased tool made by Rennsteig that has the exact die crimp design and compression ever comes into question, I'll take that hit! The goal of 110.3(B) is to make sure things are done correctly, to the recommended MFG specifications. In this case, a positive crimp of the MC4 connector to avoid loose connection, heat, and fire. Not to support a company's monopoly of a tool and their bottom line. I'm pretty sure that not everyone on this forum uses the Staubli tool.
