This imo is the modding we haven't seen with DOS's, the content adding stuff. Mechanics is where we saw most of the work. Attributed to the tool not being friendly enough and if I recall they didn't want us messing with the main game locked out, which I felt was a mistake as Bethesda sits back and makes millions as other devs fight the wrong fight.
I don't think there was a deliberate decision to lock stuff out, it was more an oversight and/or lack of resources. I don't know for certain but that's my take on it.
Bethsoft benefited from a long period of high-profile games where modding tools were created and adapted. Conversely, the modding scene has taken a bit of a hit in recent years with Bethsoft's lack of output, the likes of formerly modder-friendly Bioware going full-EA and the prevalence of online gaming locking modders out completely. But it's not a lost cause, it's just gone through a bit of a lull. In the case of BG3, we've already seen a bit of the old Bethsoft scene with Norbyte's utilities having already been adapted and having undergone a couple of revisions: while not everything is done (it's been a week!) it's now possible to make some changes even at this early stage.
