I use ProxiedMail instead of Addy and would love a Bitwarden integration like Addy has for username / forward email generation.
This can now be as easy as adding ProxiedMail to the option dropdown – they have an addy.io - compatible endpoint up, so this should be near-zero-effort for Bitwarden.
Try it out! Just use https://proxiedmail.com as the Addy.io self-host URL!
They would of course still prefer to be in the services dropdown in bitwarden so people know to look for them.
