No. Because there's all kind of stuff that is user dependent and
changes with each request. Simplest example: the trace of visited

AFAIK, the RFC states that clients should always send the exact date
they received from the webserver when requesting the resource. Seems
like I either remember it wrong or Google is violating the RFC there.
But I guess it wouldn't hurt to play along there anyway. Can you send
a git patch?
