If you have a view to the lint errors for instance at the German Wikivoyage, only lint errors are noted which were found in template and module pages. This should not happen.

Module pages have a different content model, but template pages are wikitext.

This behavior was discussed in a former task T163549 but it seems that the problem was never solved.
