The main motivation for pursuing this stage is enabling origin trials for third-party partners, to gather early performance and API usability feedback. The feedback will be used to evaluate further commitment to the current approach (formal specification, etc).

[Domenic Denicola]

LGTM.

I've filed a couple of issues that could improve the API shape, but they don't block the experiment.

I would suggest starting a TAG review and gathering signals from other browser vendors soon.
