That is quite useful however with some federated auth flows, where you just need the email to see where to send them for the actual auth (e.g. Office365 and SAML login), otherwise you'd needlessly be entering your password.
I also much prefer it to the previous way e.g. Office365 worked, where once you'd tabbed away from the email box, they'd detect you needed to be redirected and send you off, whilst most people had begun typing their passwords.
