Really interesting and needed. I am against a format that is identical to email. In my opinion this was a mistake in lightning address approach. In some cases it creates confusion. We can go UMA way (https://www.uma.me/) which adds $ in the front. I'd suggest to use ₿ so we don't have to use fiat symbol. Eg:

₿saunter@getalby.com

Alternatively: saunter₿getalby.com
