Original Summary

So this is a proof of concept to demonstrate how cross origin tracking could work in Safari. Turn consent into a captcha once and silently track the user going forward. Upsides: this could let you complete a captcha on one site, and have its grant carry over to another site seamlessly.<p>Downsides: Cross origin tracking.
