[xwiki-users] Programming rights needed for Copy Action

Hi, Why are programming rights needed to view the "Copy" Link? According to the user guide, Programming rights are described as privileges to "use protected APIs & Groovy code in wiki pages". I read the JIRA at http://jira.xwiki.org/jira/browse/XE-374 and it seems that originally, users without PR weren't able to copy pages even though the copy link was showed, so the non-viewable feature was added as a fix. What I don't understand is how copying action relates to using protected APIs and groovy code at all, or in other words, why the last editor of the page must have programming rights in order for the Copy Action to show up for anyone. Thanks Felix
