Something like this would definitely happen if someone ever allowed something like this Whenever a restriction appears somewhere, someone starts shouting that they are the exception to the rule that this restriction does not apply to.
Sometimes it's not a debate about whether it's technically possible, but rather a debate about whether it's extremely unnatural and doesn't spoil the immersion. It reminds me of a video.
If I'm reading between the lines correctly and what you want to say is that seeing a musuclar elf would be a lore-unfriendly and immersion-breaking absurdity, I wholeheartedly agree. Larian please remove Halsin from the game at once.
