Proposal tickets are no longer needed as part of the library submissions process. Instead, a normal ticket should be created once consensus has been achieved. Please see the process description for details.

Morphed this into a feature-request ticket, as the proposal effectively passed the submission process, and the patch got blessed by Edward.

I'd just like to wait until Phab:D13 lands
