How not?  When you split a live window the old window doesn't become a
parent window since otherwise any existing references to that window
would get lost.  You can ignore this fact, then Emacs works for you out
of the box and you won't need a doc-string or manual anyway.

IIUC delete_all_subwindows is in XEmacs just as in Emacs and in addition
XEmacs has (or at least had)

(defun window-reduce-to-one (window)
  "Make sure only one subwindow of WINDOW is left."
