Do Not Disturb has a great option to allow calls but ignore everything else. You can also set it to ignore calls unless there are two in a row from the same person. I keep DND on all hours of the day, every day, but never feel like I'm missing anything by just allowing phone calls. When I really need focus, and at night, I'll turn on the more restrictive setting, but at the end of the day if somebody really needs to get in touch with me the option is there. (An aside, it would be nice to be able to have a separate schedule for the "only allow double calls through" option so it could be on during sleeping hours)
