I would like to request undeploy or suspend workflow feature. I noticed that "Remove deployed workflows #2506" has been closed with the comment that currently there is no plan to implement a feature to remove or undeploy workflow; however, I believe I have a valid use case and would urge you to reconsider adding this feature. I deployed workflows with timered start event without timeout boundry event, as a result, new workflow instances are being spawned indefinitely. I tried to stop it by deploying a new version of the same workflow changing the timer start event to regular start event; unfortunately this did not work as it's treated as a different workflow even though the workflow Id is the same (ie I ended up with 2 workflows of the same Id, different version number and the original workflow with timered start event continues to spawn new instances). As you can imagine, this could lead to problems in production.
