While some gold badges are cumulable without huge effort, like Famous Question (10,000 views) or Great Answer (score of 100), it seems that the time spent in reviewing cannot be rewarded anymore past 1,000 review tasks, as the Steward badge can only be awarded once (per queue).
I propose that reviewing way above the current Steward threshold should still award something. This could maybe or maybe not help to pop the Close queue, but at least it would be nice to recognize the work of super active reviewers.
Possible rewards ideas (open to discussion):
- a silver Steward every 1,000 review tasks above 1,000. Maybe a different name?
- a gold Steward every 1,000 * 2^n review tasks for n in 0 … ∞.
