Currently all checks will appear as both checks (about content you wrote) and suggestions (about content you didn't write).
We should be able to flag a given check as being only a check or a suggestion.
Uncertain: whether this should be done at a code level (like which moments a check can show in) or via config.
Note that creating the possibility for a suggestion that isn't a check is going to require some changes to be made to the suggestions MVP, because currently the overlap is relied on for filtering out suggestions from user-edited content. (Unless such a suggestion should become the only type of suggestion that can show in user-edited content, of course...)
