Apple messes up with Pages UI - stupid ideas

Just had to help someone with Apple’s Pages, not sure what version, but they were not able to save a separate version of the file to keep two slightly different versions of a document. Turns out that Pages no longer has a Save As… file menu option, instead it has a Duplicate and Rename menu option.

Which designer in their right mind thinks that it is a good idea to change a thirty year old idiom that their entire userbase is familiar with?

Best bit of this insanity is that the shortcut key for Duplicate is the same as what used to invoke the Save As… dialog box, but of course the behavior is different.
