Actually there exists already a parameter that distinguishes between values
needed for intra-session purposes and needed for inter-session purposes.
It is the argument `markers' of the function `window-state-get'.  When non-nil,
it returns internal values meaningful only in the current session.  When nil,
it returns integer values safe to save and read in another session.
This argument could be renamed to a more general name and used for
other values besides markers.  Then a caller of `window-state-get'
could decide whether its return value is intended for the same session
or for intra-session purposes.
