Lifetime of RPMs at

I am very happy to see that is now publishing RPMs for redhat platforms. This will make it much easier to get access to new releases immediately. The question I have is how long will these RPMs stay around on the site. It would be great if they stayed online indefinitely to allow older scripts and deployments to continue working.

Does anyone know or has Docker Inc stated if they will keep the RPMs for old versions around for a certain timeframe?
