Yes.  But as I said in the thread for Bug#32672 running
'window-state-change-functions' only after a command gets executed may
miss a number of important cases where the hook should be run as well.

Once more: What could go posibly wrong if you added 'hook' to
'post-command-hook' and unconditionally (that is completely
disregarding whether a buffer display action succeeded or not) removed
the overriding action there.  If you are paranoiac about this, you can
even restore the old value of 'display-buffer-overriding-action' if
and only if the new value (when running 'post-command-hook') is the
one you wrote there ealier and leave any other value alone (because it
was probably put there by the command executed).
