Exposing would be very useful to web application developers.

Just to add some use cases.

The Ruby on Rails framework automatically sets a header called
"X-Runtime" to the number of milliseconds it took to render the body.
Its pretty handily to get this value in JS and do a window.performance
stats comparison against the backend render time.

Today, you have to inject this stat into the footer of the html to
expose it to JS.
