Looking into it. Thanks.
We have restarted work on this feature. However, we don’t have a date for public preview yet.
Thanks for your feedback! As more further investigate, the DevTest Labs supports VSTS Git and GitHub today. I’ve added this into the backlog. Given different Git repo offers different client for Labs to use and connect to, it’d be helpful if you could share with us which one you want to support first, so that the Labs can support them one by one. Thanks!
