Perhaps I have not pushed OO to the limit but for the most day-to-day tasks I've ever done, OO state is hardly the issue unless you have to write a paper or explain something via state-machine or whatnot.

Request -> App Server -> Processing -> Response -> End, no state lingering around...

I do understand what you're saying but I believe the era of complex OO with states is declining, at least at web-development level...
