> though I don't know if making your email an even stronger attack vector is necessarily one of them
I'm unconvinced that magic links do make your email an even stronger attack vector. Essentially every service that would be inclined to use magic links would already have a way to reset your password entirely once the email is compromised. All magic links do is make this the primary way to interact with the auth flow.
The bad guys already know that your email is the best target. Magic links just make that very explicit.
