'Constantly being contactable' is something of an old person's gripe, because they grew up with being unreachable by default. I walked 30 mins to school when I was 8, and took day-long biking trips with my younger brother at 14 yo without having a phone.
Almost unheard of these days (depending on where you live).
Personally I never switch off my iphone or even set it silent, but after years of living an event-driven life I learned to ignore those interruptions.
I very much want my child and anyone who may be charged with keeping them safe to be able to contact me 24/7. Too much can go wrong too fast to not be able to be there for those that I care about.
