Given our commitment to readership, this is super low priority for the mobile apps team. But, if someone from the editing team wants to implement this in the apps, then we'll happily do code review.

Can some explanation be given as to why this is declined?

It's not clear to whom this would be useful, and the current editing workflow in the apps doesn't map very well onto Schema:Edit. Once we start building further upon the editing features in apps, we'll reevaluate how they might fit into this schema, but not in their current state.

Users, especially community leaders, and for wider accountability. The data is published on edit-analysis.wmflabs.org and it'd be nice to show each of the sources in direct comparison.

That's fair; there are some issues with the schema which we need to address.

Understood. I'd recommend leaving this open as stalled, though.
