Hi!
If at some time in the future, github becomes a less than suitable environment for us, we can just move, no problem. There's no sense in which we are locked into anything.
I don't see how we could "just move" if all our bug handling would be wired into Github. I can easily see how we could move a repo to any provider that supports git - git is a generic platform, Github is just a frontend. But there's no alternative frontend for Github Issues that we could just copy the data into - you move, you lose your existing system. There are probably import tools on some platforms, but the processes, assignments, etc. - all will have to be re-developed, even if we could re-use the raw data.
