If the goal is to save space by removing menubars from applications it should be done in the proper way: re-designing these applications such that menubars are not necessary.
The only advantage I can see of doing it like this is to irritate users and developers into using/creating applications that don't rely on a menubar (such as those provided by elementary, the new U1 control panel, Google Chrome, etc). But I don't think this is the proper way to achieve that result.
To continue this course of action, an alternative method for displaying certain common actions the menubar supplies should be proposed so that developers have a sane alternative. In elementary we call this the AppMenu (the little cog on the right side of the toolbar). It holds actions that don't necessarily belong in the other parts of the UI such as the "About" "Preferences" "Report a Problem" and other entries that we've found are necessary to carry over from the menubar.
