That's a behavior change, isn't it?
Maybe people use C-x 5 1 to remove the rest of the frames on all
terminals... (I personally have never used C-x 5 1)

If we don't want to change the C-x 5 1 behavior, we can just avoid
deleting the daaemon special frame, i.e.:


+      (unless (or (eq (frame-parameter frame 'minibuffer) 'only)
+                 ;; Take care not to delete the special frame that
+                 ;; the daemon uses.
+                 (and is-daemon (eq frame terminal-frame)))

where is-daemon is let bound to (daemonp)
