That would be a dream for autistic people with heavy sensory issues. Mine are usually manageable, but it sure would be convenient either way. I've never seen any 24/7 supermarket over where I live; I guess it's just not a thing in my country (or Europe in general, from my experience).
We used to have them in the UK pre-covid. My local Tesco and Asda were all 24 hour, except for Sunday trading. Now, barely any are open around that time.
Surely there are some people that prefer the night schedule. The problem is capitalism and wage labor, not the fact that there are "inconvenient" schedules for most people.
