Yes, weights are the PREFFERED FORM FOR MAKING MODIFICATIONS!!! You, the labs, and anyone sane modifies the weights via post-training. This is the point. The labs don't re-train every time they want to change the model. They finetune. You can do that as well, with the same tools/concepts, AND YOU ARE ALLOWED TO DO THAT by the license. And redistribute. And all the other stuff.
