^/release/*/source as branches named 1.9-release, 1.10-release, etc.

Do you really need these branches? (For backpatches?) The Git allows just
to tag a some commits
to mark them as a release points.

Seems to be enough.

Yes, and there is a way to make releases automatically via the Github API
as described at
https://developer.github.com/v3/repos/releases/#create-a-release

Let's give it a chance. ;-)

I would like to help with automatic creation of "releases" via the GitHub
API,
but I'm really busy in near month.
