It's incorrect that salted hashes are obsolete or quickly attackable per se. Password hashes are a subset of all hashes. Therefore they are hashes. bcrypt uses an internal salt (as it says in the first two sentences of its Wikipedia page).

Salted hashes have been irrelevant for at least 5 years, possibly more. It was a big deal in 1995-2004, back when "Rainbow Tables" were a thing. It just doesn't matter any more, and hasn't for a long time.
Don't be misled by the fact that bcrypt/pbkdf2/scrypt both use hashes, and have salts on the front - that's just a property of them, not their primary essence.
I think the right thing to say is that password hashes are all randomized, just like a salted hash --- but that when you say "salted hash", you are evoking SHAx(password, salt).
So what is their primary essence?
