Yeah it's definitely a better pattern, I hope more companies create something like it. I think I heard Apple is doing something similar maybe? I seem to recall Fastmail has one too, pretty sure I saw it in the bitwarden settings last I went in there.
Apple does this with email forwarding aliases on your phone; I can sign up using a generated Apple relay, which then pushes to your main email. I don't like it that much, mostly because you're still kind of locking into the Apple ecosystem, though.
