Mimiran Ideas

Back in the day, people really liked having subdomains ("mycompany.mimiran.com"), but this is becoming less and less common. I went to some trouble to implement it, but sometimes people complain that they are not sure where to go to sign in, if they want to rebrand it's a nightmare, etc. What do people think of everything being the same, except that everyone would sign in at app.mimiran.com? (Existing links to proposals could redirect.) Everything except the login screen would have your account colors, logos, etc, and of course the same security.
