People have been doing this, but the majority doesn't have this sort of flexibility[0]. Particularly any customer-facing job is going to require being there at a certain hour.
[0] Those who do typically could well be working remotely instead.
I think it doesn't need to be a majority for the situation to be a net improvement.
Among my colleagues (~20 people) nobody has a customer-facing job, and only one needs to manage children. The others either don't have kids at all, or the kids are old enough to manage on their own. They all come in the office around 9:30 AM. We rarely schedule meetings before 10 AM and after 5 PM. I'm pretty sure that if even 10% of the people would change their schedules a bit, comfort would improve for everybody. It's the same thing with lunch. Everybody goes down at 1 PM on the dot and complains about there being too many people. I go around 12:30 and never have to wait in line for ages.
Of course, WFH would be even better, but I understand not all people like it. The company I work for is actually quite flexible, but the people do tend to prefer working from the office. I, personally, prefer WFH (which is what I do generally). But my point isn't to push a particular working arrangement, rather to point out that even when there is some inherent flexibility in the system, people seem to choose not to use it.
