Houseparty’s culture is to mostly just enter and leave as you please. It is nice. None of what you described as issues.

Similarly in a remote coworking community I started in 2019, we have also settled on a culture of not worrying about “politeness” when it comes to coming and going. It is so much better.

Of course like you say, to have all of this work for people across the board is a much harder feat.
