Some of these are nice ideas, but they're largely impractical.
Writing up a full review on an incident, what happened, and how what conclusion was made? There's already been 60 reports, so that's quite a bit of typing.
We also do have stewards outside the series involved, if only one. You give us a list of willing people that are known to be trustworthy and have the free time and will to do this, (that don't even take part in the series) and I highly doubt we'll turn them away.
It's a lot of work, yes, but it's the way things will be smooth, in my opinion. That's why I am suggesting to bring more people from outside the series, neutral people, to help with incidents. But like you said, it isn't easy to find people with enough free time. That is the BIG problem here, I guess. I got a fair amount of free time most of the time, but since I am a driver I dont want to make decisions on incidents as Im sure I would be having bias decisions.
