Focus is quite robust. You can have multiple focus modes, each with custom aways, which can be shared or not, each with custom notification behaviors by person (or group, like favorites) texting you and by app trying to notify, and shared across devices or not. Prior to Focus, you could abuse the “dnd while driving” option to reply with a long custom text message. But Focus is well thought out as a way to make all your apps behave.
