I'm not convinced.  Pointer addresses have the clear disadvantage that
two runs of Emacs will give different results for the same sequence of
window configuration changes.  Window parameters mean that one has to
externally manage some sort of mechanism to assign unique identifiers
(strings or numbers) and run on `window-configuration-change-hook' first
a function to detect for each split the new parent window and the new
live window and assign them the appropriate values.  Clearly nothing for
emacs -Q.
