Comment 13 for bug 52805

Numérigraphe, I don't think 'discard suggestion' completely fixes it, though you do have a point.

The problem here is that someone might not be a reviewer and might want to discard their own previous suggestion: the way to do that is eg. to only keep the latest suggestion by a single person.

And the way LP implements external suggestions, a bad suggestion would still show up as a suggestion on other projects as "Suggested in ...".
