But it would be interesting to see some stats on the relative retention and upgrading of editors who use monobook and Vector.
The idea sounds crazy, but yes, why not, let's test this. I believe you can put your thoughts on a Meta-Wiki Research: page, describing the background, the A/B test and the proposed analysis, and then ask the WMF to run it (preferably with the consensus of the target wikis, but it's not usually considered necessary for so-called experimentations).
