Anne, Ian, Simon, Robin,

Do you have a preference one way or another for either of the above APIs?

I have a git repo <https://github.com/majido/scroll-restoration-proposal> where
I have spec'd the first option
<http://majido.github.io/scroll-restoration-proposal/history-based-api.html>
(as
implemented in Chromium) and am tracking issues against it. Unless there is
a strong preference against #1, I feel it is reasonable to try to ship it.
