Meetings which decide things are very hard asynchronously because they empower both not deciding, and veto by non attendance.

I'm not saying it always happens but if a decision has to be made and it's Round Robin (which is what asynchronous work implies to caucus everyones sign off), it's going to take several orbits round to avoid toxic gaming of the mechanistic side, where a synchronised event would be one and done if the decision is a vote or consensus.
