It would be fine, and customers ask me for that continuously to have the function to again start a failed pipeline,but not at the very beginning, rather at a stage along the pipeline chain, particularly a stage which failed before during a former run,and the cause of the failure was fixed.
Maybe I've chosen the wrong "component" for this ticket. Please feel free to adjust accordingly.
Tested on Jenkins ver. 2.0-beta-1, and its new Pi Pipeline item.
