I'd like to request an official position on the Heavy Ad Intervention.

Explainer: https://github.com/johnivdel/heavy-ad-intervention/blob/master/README.md

WICG/Interventions Issue: https://github.com/WICG/interventions/issues/68

HTML Spec PR: https://github.com/whatwg/html/pull/5885

Chromestatus: https://www.chromestatus.com/feature/4800491902992384

Other information:

This is a browser intervention which unloads ads that use an egregious amount of system resources. While we aren't proposing a full spec for this intervention, we are proposing an update to the HTML spec which allows user agents to unload iframes/embeds at will. 

Any feedback is appreciated.

Thanks,

John
