That's because that's essentially what this is :)

And yes, that's how Relay for email works (although instead of using mydomain.com, you use mozmail.com, so your different email masks can't be linked together).

We'd definitely like to support a similar pattern for phones, but we still have to figure out a way to do that. Using extensions is one thing we'll be looking at (was also suggested at [1]), but a challenge there is that many services have rather strict validation rules on phone numbers that will disallow that. But it might still be worth it, so stay tuned!
