I mean that is just due the bizarre idea that every character needs to be equally good in combat. Bunnies are way better at hiding than rottweilers and a lot of cuter too! Like sure, we want characters to be able to contribute in some manner to most aspects of the game, but this does not require that they must contribute equally all the time. Worf is a lot better than Geordi in combat, but Geordi is better at engineering (though both can do both a bit if needed.) I think it would be way healthier to think balance more holisitically, and lot of non-D&D games do.
But if we accept axiomatically that genuine differnces cannot be depicted due balance, then why the hell we are having different species at all? If what you effectively have is just various cultures of humans, then be honest about it and have that!
