Publish in its generic form takes a few steps to set up and often my colleagus first want a set of hard copies to mess up , later they want single pdf's and five seconds later , nah , can you put 'm in a single pdf. That's why I have all options under a couple of buttons myself. Also I often have drawings coming from different sources and don't want have to do pagesetup first so I can imagine it can come in handy to be able to select a folder or a project file with drawing names with one click and with another say plot , pdf or publish.
