Given some shifts in the way we're thinking about some other concepts, I've written up a short proposal at https://github.com/mikewest/strict-navigation-security that builds upon and simplifies Apple's proposal. We discussed it briefly at yesterday's webappsec meeting, and there seems to be interest in doing something in this space.

If not, would y'all be comfortable with us defining some web browser behavior/Fetch integration in webappsec that constrains the existing RFC?
