Full disclosure: I don't really want to return to 100% office requirement either. I'm really excited to see other humans again - though I suspect we'll see a 2-3 day a week in-person expectation and then 2-3 day flex moving forward.
Now, many of those things are probably good for the business anyway, but they are nevertheless obligations that remote workers force on their colleagues in order to achieve that cleaner, "API-like" working relationship that remote workers often need to succeed independently.
It's even more stressful if some employees are gelling well and some aren't. Many remote workers feel they should be treated like contractors but given fuzzier expectations like salaried workers - I've seen this misalignment of expectations about culture destroy teams, and in an office culture transitioning from full time in office to partially remote, all of this is fundamentally caused by the "benefits" that the remote workers are receiving at the cost of their colleagues. It's absolutely not a win-win.
