Typically, agile teams may not classify work that is a bugfix with Story Points. It would be terrific if there were a way to measure the amount of points for bugs for later analysis. Support for a Bug Points field would be great in being able to determine the pace of work on bugs versus the pace of work on conventional non-bug cards.
Also see T78361 - plus not sure how much the differentiation between bug points and story would clutter the UI. This is not an upstream issue as custom fields are up to our own configuration (plus at least picking up story points and showing them on boards is done by the custom Sprint extension)
