I have developed a gadget that enhances the process of adding translations to a Wiktionary entry. It performs an edit action on the page via API. At the same time, a locally defined tag is applied to the revision through the corresponding API parameter: ?action=edit&tags=xxx. I have noticed that for this to work, the editor must have the applychangetags user right (do not confuse with changetags). On WMF wikis, it is granted by default to all logged-in users. Is there a reason why it is not for unregistered users, too?
