Ryan, I love that you are interested in security UI design and I don't want to discourage you. This issue is complex and it's not easy to hide whether a user has an account with us. It's a leaky sieve, and locking down all the holes might introduce unfortunate UX compromises.
Google gives you a
The username or password you entered is incorrect.
to disguise whether the username exists or not when you try to log in, but they'll reveal whether a given account exists or not here:
Type in your existing username they'll tell you right away whether that username is claimed or not:
Someone already has that username. Try another?
However, the sign in and sign up flows will have different rates so we can throttle them differently.
I've re-opened the issue with engineering, so we can discuss further:

Type your password." This was the logic we used when coming up with the sign in flow for payments.
