The previous plan for assessing the current state of affairs was via adding request logging capabilities to various parts of the labs infrastructure, but that's a huge dependency that's not up to us to resolve. Therefore, I propose to add EventLogging tracking of the following features:
- WikiMiniAtlas
- WIWOSM
- GeoHack
This should work on top-10 Wikipedias (because these features are user-added, making it consistenly work everywhere is a gigantic task).
