Rolling Back to a stable version is the best professional solution for people who work on live projects for clients and for whom workflow is critical. We can go without all the shiny bells and whistles if it breaks our workflow and causes time loss.
We should each definitely take responsibility and implement our own backup system and probably run Dual Versions if we want bleeding edge but having an easy Rollback feature built into the software would provide a good stopgap measure while allowing us to Test. That is why I opened the new feature request.
