I wonder if the folks who say this is an "odd idea" or "NOPE" have actually played BG2 and know what the others are even talking about. It's not like this was any real "world building" stuff. Just some fun mini quests for the player to goof off with that also make your playthrough feel more unique.
I doubt Larian will add something like this though.
It's not like if BG3 was inspired in any ways by BG1/2...
But yeah, this.
