> It's not the design.

By design a minibuffer is a special buffer and a minibuffer window is a
special window.  The concepts of a standalone minibuffer window are
mostly unchanged from that of a minibuffer window attached to a normal
frame.

You either have to redesign the concept of minibuffer windows or work
around the design.  Both tasks seem non-trivial to me.  "Right now" is
just another way to express that.
