Reverse scheduling

I'm currently using a slightly modified version of the workflow module, which uses Reverse scheduling. I had the following case: I was supposed to create a workflow, where there were three stages not edited, under editing, finished. The problem was that once getting in the phase of "under editing", there was the need to create an intermediate stage, where the node will be not visible for the user until he or she decides to see it again, where he or she was supposed to choose the time when it should happen. Under the present system of workflow there was not such an opportunity or I was not able to figure out how it should happen. Therefore, I patched slightly the workflow module and now it performs the following additional action,

which I called Reverse scheduling: the user is able to set a time when the node will return in its previous stage

. I would like to know if there could be some interest in such development of the module.
