Just to clarify, the "disabling" mentioned here is about removing it from the Wikimedia cluster and thus making it impossible for any interested wiki to use it, not about disabling it on the few wikis where it has been enabled so far. Whether this is a good idea or not is being discussed now at bug 61163 [1]; if you are ambassador for a wiki which is planning to use or trial ArticleFeedback, you should probably get involved. (The tentative date of removal is start of March.)
