Because now developers can just think. "He it keeps the page out of the session great i will return true"
But that is dangerous if you use any state (urlFor call basicly) because those will not work,
you always get a Expired page of course..
So the developer can't really decide if a page is stateless yes or know. We as a framework can.
For exampe a developer can make a page stateless and in the beginning it is stateless yes so everything works
Then suddenly a small change happens and suddenly errors are popping up (hopefully they test this right as soon as possible
and they know immedianlty why they suddenly get an Expired Page when they do X)

maybe the IRequestCodingStrategy is the place to keep track of this. if
the coding strategy is used, then the page is stateful. the urlFor
impls all call it and there might be more cases in the future.
