DirectDeploy For Preproduction And Production

I'd like to request the ability to use DirectDeploy on both preproduction and production as currently the option is only available for integration. I understand that during the DirectDeploy process the site becomes unavailable, which you'd typically want to avoid for a production deployment. But there are scenarios where a fast fix is needed opposed to having to wait for the normal deployment process to complete. One such scenario is if there is an unforeseen error with a deployment that causes the site to no longer work properly or simply throwing a site wide exception.

Some companies can lose a substantial amount of revenue the longer their site is down. Having the DirectDeploy option would minimize revenue loss by being able to recover faster...even if it means the site incurs a slight outage. I would think most reputable companies would be wise enough to not enable DirectDeploy as part of their primary production deployment process, but having it in our list of possible recovery options would be a benefit to anyone who is having a critical issue on their site.
