Backdrop CMS support?

Hello, and thank you so much for this wonderful module!

We've been working on a port to make Styleguide work for Backdrop CMS (see https://github.com/backdrop-contrib/styleguide) and we're wondering if the maintainers of the Drupal module would be interested in also maintaining the Backdrop version, or if you don't have the time or interest, if you would be open to continued collaboration between the two projects?

We've been making a few small changes / additions that were needed for creating a new look/feel for the administration theme. I'd love to contribute these changes back to the Drupal 7 version of this module too, incase anyone else is also useing it for building admin themes.
