Ask HN: Shared DevOps for OSS. What would it look like?

A friend and I were arguing whether a "shared devops platform" servicing OSS projects, would be helpful! Many OSS communities I've interacted with, have very little time and resources. Setting up your typical servers (CI/CD, irc, mailing-list, web servers, DBs...etc) just eats a lot of time, let alone baby sitting all this software (security patching, backups...). Yet, almost every OSS project has to do almost all of that.

So HN, do you think a standardized devops platform where any OSS project can get managed standard software stacks helps OSS projects thrive faster? What would that platform look like ?
