Not sure what you mean by " 'publishing layout view' bar" - there is nothing
by that name. Perhaps you're referring to the Elements Gallery containing
the buttons for Publication Templates, Quick Tables, Charts, etc. If so, the
answer is No, the Gallery is a permanent fixture. However, you can go into
Word> Preferences> Gallery, remove the check on "Open Elements Gallery when
application opens" in order to reduce the EG's height to display just the
buttons, but the buttons can't be hidden or removed.
As for who uses those features - well, you might be surprised
I honestly
haven't seen any that I would describe as "rainbow", but even so the layouts
are exceptionally creative & professionally done. Most importantly, their
default content does not have to be retained - it can be replaced by the
user's graphics or deleted altogether just like the placeholder text. Used
properly the templates can save quite a bit of time & effort for those who
have a use for that mode in the first place - Publications.
