Dito, have been doing the same with a selfhosted mailcow for years. Never had a problem :-) Lately I started switching over to [e-mail] style because of the automated organization so I don't need extra routing rules if I want to organize them.

Except for the sites that reject the + character in email. I curse those developers who do that and never go back to that site again.
