I wouldn't write it is "chaotic".  The behavior you consider "chaotic" is 
well-defined, and has been there since Emacs 21 at least: the minibuffer 
moves from frame F1 to frame F2 if and only if the minibuffer is active on 
frame F1 and a recursive minibuffer is entered on frame F2.  There are 
other possible behaviors of course, but IMO the current one is a 
reasonable one.

There are at least two Emacs users on this list who use minibuffer-only 
frames: Stefan and Drew.  I'm also curious why they do this, and would be 
interested if they could explain what the benefit of doing this is.
