I guess if you're not willing to press a few extra buttons every time you make a new login you're right, there's no alternative.

Personally I don't make new logins that I need "full" anonymity enough that I value those clicks over the massive downsides of supporting proton.

Id be cautious about assuming the emails can't be traced back to you. After all, proton (or anonaddy) is storing the mapping unencrypted by definition.
