Hi could there be some sort of support for comments in the extension.json and skin.json files without causing problems like you can in the .jshintrc file which is a json file but can do comments. Please see https://gerrit.wikimedia.org/r/#/c/209882/
There should also be a global specification on what a wiki developer should do.
Should they put the comments in the json file or should they put them in the README file or should they have them on the mw page.
It is causing patches to sit for a long time because a developer doesent know what to do.
