Btw, assuming that more levels can be added, there will be a problem: imagine that an app hooked up onto low, med, crit levels in "strict" mode... then once we add a new level, the app will start missing the new level events.
In the old scheme it is not a problem because of the >= condition.
With a proper versioning this won't be a problem for a new scheme too.
