Yeah.. this is one thing I recently discovered. I use github for my personal projects, and was going to start using the issue tracker to keep track of the bugs. But then I realized that if I do that if I do start tracking bugs on github, I will pretty much be tied to github.
Hopefully gitlab or bitbucket comes up with a solution which enables the owners of the repos to move bugs/issue tracking, which will force github to enable this feature as well.
