While I agree with your first statement, I think it's more of an unintended consequence of the "qualified" and "unlimited" license scheme that is in place.
If we were to propose a law completely removing the restrction of unloaded transport, they would just point to the "shall issue" nature of the "qualified" permit and say that people who want to go shooting can get a permit with very little hassle... even less now with lifetime licenses available.
This new proposal is for people who don't shoot, don't carry, and never will, but are possibly felons if they just want to learn how to use their gun safely.
