no one works in a vacuum. people need to communicate and collaborate, even when the work is prescriptive. core hours requirements stem from making sure that there are times when everyone can have rich, immediate interactions. not from childish supervision.

"There needs to be some time when everyone is here, so that we can talk" does not imply "you need to be here for 8 hours a day".

In theory, you could have a job where the core hours are just 4 hours a day (most coders do not spend more time having rich interactions), and if you succeed to get your work done, you can leave afterwards.
