I can agree that internally the wiki has to load the module page etc which would be equivalent as using an expensive function. Same can probably be said about using templates in that case.

But I was talking about the explicit "expensive functions" counter. this page on our wiki uses 5 modules (2 with mw.loadData) and shows a count of 0/100 expensive functions.
