Technically they are but also same time they're not.
It means it's still hack but legit hack meaning limit are not bypassed.
I could bypass it with 999 stats and 255 ev for all 6 point but that would be cheating because I bypassed the limit.
But when I modified your Pokemon, nothing's bypassed, it even passes legality checker so it's all good.
What are you talking about? You already forgot?
I said I'm gonna nevermind(NVM) that and just gonna modify illegal pokemon you give to me straight to legit pokemon.
So I didn't breed anything, I just modified your Pokemon and turn them into legit IV'd shiny.
