Why not have both though? And we already had, with Tasha's optional rules. As I've said earlier, you are actually the one who wants to force restrictions on a considerable amount of players. Your way of playing the game already perfectly works within the system that pleases both types of players AND has an in-built logic that separates the species by their abilities. It is just not logical to have world defining metrics like abilities and say that they should not define the inter-species differencies. You'll take an orc for your character, but it actually won't be an orc, because he'll lack a considerable chunk of the 'orc' part. Maybe I am not understanding something, but apart from some slogans and personal feelings you haven't explained why this is better than what we have now.
