This task involves the work of updating Special:EditChecks (or some other, more fitting page) to include an aggregate count of how often a given Check/Suggestion is shown.
Story
As a volunteer who written a new Check/Suggestion for my wiki, I want to see a count of how many times it has been or would be shown to people within actual edit sessions, so that I can decide whether it's worth fine-tuning. If the Check/Suggestion is showing (or likely to show) rarely, I'd probably stop further development.
