Do you support VersionPress (Git version control)?
ANSWER: Yes, but only for Enterprise level clients, along with its dependencies (Git, etc).

However keep in mind that using VersionPress as a remote staging service is not really possible yet, because their current release require WP-CLI (managing via SSH) and do not offer a user interface yet. We are following this closely, and may end up offering something related in the future.
