This is true already for pretty much every website that lets you recover password by email, and most allow this. Any that use a secret question wouldn't switch to this scheme anyway. It reduces the hassle, as if your email got compromised, and they change passwords to all your other accounts, you have to regain access one by one, changing passwords back and so on, when with this email system, you can just regain access to the email account and the rest are under your control again.
