Yes, this is non standard, but it's supported by SpiderMonkey, and that's what gjs uses. It's an implementation detail anyway, and its purpose is to have callable objects whose prototype is not Function.prototype, so that you can have const MyClass = new Lang.Class(...); and "MyClass instanceof Lang.Class" becomes true, even though MyClass is a constructor (function).
In any case, this kind of question is better asked in a specific mailing list, such as gnome-shell-list (most gjs devs are there) or javascript-list. Alternatively, you can find us in IRC (#introspection, #gnome-shell or #gnome-hackers).
