When we believe a Feature is ready to be implemented, we want to assign the Feature description a version number so that everyone knows what version of the Feature description is being implemented. If the Feature description subsequently needs to be updated (as sometimes it will) we can then agree which version is now being implemented. At the moment it's too fluid. We need to be able to retrieve a specific version of the Feature.
Thank you for the idea. Given the low volume of support for this idea, we do not have plans to make updates in this area at this time.
