I have been arguing for contact states for years. You should be able to set conditions like the old IM status messages - "away," "in a meeting,","family time,"etc - that limit your reachability and optionally notify people that you won't be notified of their messages (until a certain time, if scheduled). This was (naively) my first iOS app attempt before I realized this is something that has to be done at the OS level. Please, Apple, "Do Not Disturb" was a step in the right direction. Finish the job.
