Hey Rob, Thanks for posting this so quickly, I think it's definitely a step in the right direction. I've posted this as a merge request on gitlab [1] with the reverts squashed into the change. I don't think this will conflict too badly with Alex's work, but I want him to take a look at it first before merging.
