Very dumb to not pick a bloodline. Uchihas can’t be identified on sight. Neither can Senju. There are others that are that way as well. A black haired baby? There’s tons of them. Unless you KNOW a person is Uchiha or you see a Sharingan, there’s no true way to identify them as an Uchiha without genetic testing. Senju appearance varies widely. Look at Hashirama and Tobirama. They don’t even look related. Tsunade? Barely has any resemblance and is blonde. Nawaki? Again, looks vastly different. I can see not picking Uzumaki because they are so easily identifiable.
