@Ursuul: for this update, we concentrated on the most commonly seen modules. Anonymous viewers make up by far the majority of visitors to the site, who don't see modules like Insights and JS status. That said, we are going to be working on updating the others.

@Digifiend: We have not announced that achievements is being axed - only that it is deprecated. The only technical change was the removal of the switch from WikiFeatures - but we are still happy to enable and disable it via Special:Contact requests.
