Also, one of the reasons while nesting langSwitch in templates works here, is because our templates are (usually!!) not that complex. I'm currently working towards getting Template:File info internationalized through replacing the text in Template:License switch with localized copyright texts such as Template:Copyright-unknown. This means the following levels of nested templates:
 * langSwitch used in Copyright-unknown
 * Copyright-unknown (and many more) used in License switch
 * License switch (and many more) used in File info
 * File info on every single File: page.

Template:File info is one of our more complicated templates, but I think on your wiki it would likely be only the average.

There's one more wiki that works like this wiki, which is w:c:VSTF. What our wiki and that wiki have in common is that they are for certain "services" (WLB: for requesting translations/corrections and international spotlight, VSTF: for reporting spam and vandalism). It's to make sure our teams would not have to check the edits on 20 different wikis. On a content/encyclopedic wiki, having a WikiActivity with only English edits or only Spanish edits on the other hand is not a disadvantage.
