In any event we're still talking custom character options here right? Not changing the look of a prominant Elf companion, or the majority of Elf NPCs we encounter. So it really only affects the protagonist. Many people are just going to want a PC that looks like an idealized version of themselves. Still others are just going to play as an Elf for metagaming reasons, because they want dark vision or a bonus cantrip or whatever, not because they want to look like an alien Vulcan per se. For Tav the more options the better.
