Maybe you never visited the page or your cookies are expired (or you logged

And visiting any page (with all cookies/other headers) is irreversible action.
It affects statistics, it could do something without your knowledge (marking
message as read in your webmail?). Yes I know about special header browser
should send to a server, but I've never heard about any site supporting it.

Visiting a page should be a "safe" action; we shouldn't design
extensions to address cases where people get this wrong.
Also generating a whole page just for metadata in it is a waste of server's CPU
time.
You don't need to generate the page (there's the HTTP HEAD method).
