And printing out a schedule for every child is a bit silly when there is calendaring software...

Everything once done on paper is now done electronically - and revisions (fixes) happen much more quickly to boot.

You're not wrong, but, my school timetable changed once every quarter, that was sort of feature. It's not work, no one is flying in from $city on $day to kick off a project, students and teachers would follow a routine, it was easy.

Frankly there are some aspects of it I miss...

Wut? Does the school do anything that involves stuff that you need to dress differently for?

Even when doing PE I’d always bring a separate bag of gym clothes.

It is literally the same thing then. If one is not causing outrage, nor should the other.
