You mean to do away with the KEEP-WINDOWS argument and keep windows iff
`window-state-put-keep-window-functions' is non-nil?  This would be up
to you to decide.  Only some practice can tell what's better here.

For some time we don't run hooks any more when windows and their buffers
change but rather wait until redisplay detects that some change occurred.
`window-state-put-keep-window-functions' already opens the backdoor to
the previous behavior so I'm not sure about opening it even further.
