The doc-string of 'redirect-frame-focus' says:

   A frame’s focus redirection can be changed by ‘select-frame’.  If frame
   FOO is selected, and then a different frame BAR is selected, any
   frames redirecting their focus to FOO are shifted to redirect their
   focus to BAR.  This allows focus redirection to work properly when the
   user switches from one frame to another using ‘select-window’.

   This means that a frame whose focus is redirected to itself is treated
   differently from a frame whose focus is redirected to nil; the former
   is affected by ‘select-frame’, while the latter is not.

The Elisp manual says almost the same:

      Selecting a frame can also change focus redirections.  Selecting
      frame ‘bar’, when ‘foo’ had been selected, changes any redirections
      pointing to ‘foo’ so that they point to ‘bar’ instead.  This allows
      focus redirection to work properly when the user switches from one
      frame to another using ‘select-window’.

      This means that a frame whose focus is redirected to itself is
      treated differently from a frame whose focus is not redirected.
      ‘select-frame’ affects the former but not the latter.

With Emacs 29 both texts have become false.  Selecting a frame no longer
shifts focus to that frame.

That change has immediate consequences for interactions based on
read_minibuf.  With emacs -Q evaluate (make-frame '((minibuffer . nil)))
and in the frame created thusly type C-x C-f.  At this time it is
impossible to access the minibuffer-less frame using C-x o, C-x 5 o, the
window manager's Alt-TAB or any other key combination.  All these key
combinations used to work in the given configuration ever since.  With a
minibuffer-only frames setup, the minibuffer window has become "modal".
