I'm curious, why not migrate?

edit: Sorry, I'm stupid.

For one, not everyone uses git and GitHub for everything. Some prefer Mercurial and Bitbucket.

Bitbucket doesn't prefer Mercurial. Bitbucket Server only supports git.

... just to use a CI tool?

You would also get Review Apps which are pretty sweet.

I work for Heroku, review apps is one of my favorite features we've launched.

Any chance to get review apps for GitLab and/or Bitbucket? I'd love to see that happen, but I don't believe it is high on your roadmap currently.
