On en.wikipedia.org template vandalism is well known and vandals get better at
finding interesting templates. A well established countermeasure is to protect
templates, especially for those transcluded into articles linked from the main page.
Checking the protection status of the pages transcluded into a page would be
easier if the protection level would be displayed in the list of transcluded
pages in edit mode.
I suggest to add the text "(protected)" or "(semi-protected)" next to protected
entries in the list of transcluded pages. Not protected pages would have no
