GP wasn't asking about the files being immutable, whatever a mutable file would mean. They were asking about the releases. I'm curious too.
The way it's done with rubygems, if you messed something up with the gem (pushed secrets, etc.), you "yank" (remove) the release and push a new one (different version). You can't work with the files in a release once it's been pushed.
