What if the update involves the javascript engine or fixes a bug with the
cookie jar. Things are different after an update thus its impossible
to completely restore the experience. Newer web application will maybe,
probably already handle all the save state stuff, data in real time. The
browser just has to get you back to the location.  If the website can't cope
with something simple like that the user will probably blame the website.

of course this is my ideal explanation.
