actually I would rather they not add any crafting to BG3. crafting not really well done in 5e books and would much better if they focused on adding more story or making game more 5e like then spending time on a crafting system. Not every game needs crafting.
Well, Larian already heavily homebrewing. Why not give them a chance to fix thing, that Wizards were failing fixing for years.
They surely can learn lots of things from Pathfinder, as well as 3.5e.
