Since I'm the data analyst on the Editing team, I'm generally responsible for movement-level metrics related to editorship. I have a lot of ideas for how to improve or expand these metrics (such as a session-time-based active editors count and a robust breakdown of edits by tool used to make them), which I hope to have time to develop at some vague point in the future :)
Will the Wikistats 2.0 structure be elastic enough to accept these kind of modifications if, after all due consultation, they are ready to be adopted?
