Seems like there are two separate threads here then:
1) proposal to add 'network duration', which excludes blocking and cache
times... but should (for correctness) include redirect cases [a]? The
latter gets real tricky with cross-origin redirects.
2) exposing 'network duration' without TAO restriction.
I have a feeling (2) would be a really hard sell as we'd be exposing an
explicit cache vs. network fetch signal, and in effect circumvent current
TAO restrictions. As for (1), it's a computable metric... as such, we're
only talking about convenience - right?

Thanks Pat! Really curious to see the results...
