For me the issue is that this is presented as a great thing that only hybrid offers. But it is the thing that full remote offers, too. And you're quite lucky to WFH 3/4 work days (also to have a 4-day work week, I guess, if that's so I'm really glad at least someone has it already)
My company doesn't enforce office at all, it's just a measly 40 working days per quarter that we are required to come to the office. I agree that it makes sense to see each other in person every now and then, it's just the way it's done doesn't really encourage planning to gather a team at the same location, just ticking the checkboxes
