Arbitrary orientation/gravity direction for Characters

This was posted on the Trello roadmap June 2014, and I was wondering if there has been any further development on this.

To my understanding, it would allow for a Character to be able to walk on walls, objects to fall in a different direction, etc. This is something I’d really like to have for my game.

This was added to the 2017 Backlog on the old road map. Is it still a feature we could look forward to in the future? The new road map doesn’t have any of feature being considered anymore, only ones that are approved for the next release.
