Also, opt-out rates tend to be low no matter how obvious and desired they are. If the goal of this analysis is to find out if opt-out rates are high (or low), then I'd recommend comparing them with opt-out rates for another feature.

One thing I did was to compare opt-out rates with other wikis where we have received fewer complaints (fr, es), and enwiki optouts seem to be in the same range. Do you think that is a useful indicator, or comparing optout rates for wikis with a different userbase size is not particularly useful?
