Why not use the name attribute to split the geometry into multiple mesh prims rather than use geometry subsets? The name sop can create names from existing groups. I've found geometry subsets sometimes have funky behavior with materials bleeding from one subset onto another.
When you have more than 300 pieces imported from a modeler that didn't name all, it's kinda hard. That's why assign by groups is good
How is that different? Creating groups from a soup of unnamed geometry is just as much of a chore as coming up with name or path attributes. It's probably more of a chore since VEX makes it easier to procedurally define name attributes than to create groups.
