こんにちは TAG-さん!

I'm requesting a TAG review of a new speculation action of prerender_until_script. This proposes a new action for the Speculation Rules API, prerender_until_script. This action is designed to provide developers with an intermediate option between the existing prefetch and prerender actions.

@domenic and I are both no longer working directly on this at present (and Domenic is no longer affiliated with Google), so we probably shouldn't be listed as primary contacts.

@jeremyroman I've dropped you from the "contacts" list. @Clqsin45, feel free to add anyone else who's actively working on this project.
