I'm assuming the grab/pinch values in code are an mistake, though I suppose 1.f and 0.8 for grab and pinch strength could be for stability reasons. I personally think a lower value makes more sense because it's easy for a user to add more stringent checks in the blueprint implementation, and pretty much impossible to make it more lenient without digging into sourcecode.
