I would like to say that while I do get OP's point, I believe that elves should look more otherworldly, as several people here have argued as well. It would also provide the option OP wants in the form of Wild Elves and Wood Elves. However, if Larian really does want to make elves nothing but "humans but with cool pointy ears" then there really is no reason not to add diverse facial types. Though, as unrealistic as it is, I would prefer BG3 Elves to be remade to look more alien so to speak.
I also agree with the slightly off-topic point brought up here that the creator should definitely feature sliders. Sadly, that is also an incredibly unrealistic idea thoigh.
