We sometimes need to update that plans have changed, that an event didn't come to fruition or that changes happened that resulted in rescheduling part of the event, so the event needs to be updated in post to implicate that. for example, if we hosted a watch party and expected to watch 2 episodes, but only watched one, it'd be nice to be able to reflect that change in the past event, instead of spelling it out in the next scheduled event and having to link back and explain what happened.
