I noticed that the event is disabled by default.

Is it because of concerns of too many events, or too much overhead? Or something else?

I think we should strive to have events always on. Few users will take the time to learn about the event and enable it. Usage will probably drop by 99%, if not enabled by default.

If concerns are performance related, there might be other event designs that could be used, for example, a periodic event that is always enabled.
