Why not?  Have you ever seen windows deliberately change places on a
frame?  Atomic windows are glued together like a window and its mode
lines.

That's what the 'no-other-window' parameter is for.  With the slight
difference that with a window you can turn it off temporarily.

XEmacs has it, IIRC.
