I have been low-key lobbying for the utility of moderation audit logs for over a year and I think it’s in scope for the SWICG task force, so opening the same issue here might help more than asking any one implementation to be the first to implement audit logs in a given format?
I think some kind of uniform logging (that might even be neutral enough to wire formats that it would work for events/events from other protocols or for objects defined in FEPs/extensions to AP) is already being discussed in that task force, so one more vote for the basic idea in a public, official place would probably help the cause even if you don’t have time to contribute otherwise to the TF
