Since we shipped the first Deprecation Trial, we have also shipped the non-cookie storage extension to SAA <https://groups.google.com/a/chromium.org/g/blink-dev/c/F5EV8I-j7Eg/m/OAi7lcykAAAJ>(M125+) to address sites impacted by storage partitioning. We are confident this API extension will address the majority of “unpartitioned” storage use cases, however, we are aware of a few partners with slightly different use cases that we are currently exploring API solutions for. Our near-term goal is to have this Deprecation Trial expire and migrate the platform to partitioned-by-default 3rd party storage, communications APIs, and service workers, especially ahead of 3rd party cookie deprecation. Given that, we propose to only allow an extension for sites that have already enrolled in the current non-expired Deprecation Trial, taking advantage of the new OT registration approval workflow. *That's exciting! Are there numbers you can share regarding the current participants? Is it realistic to expect the 6 milestone renewal to be the last one?
Sure thing - we have on the order of 600 registrants, but if you de-dupe the list that takes you down to about 400. Further removing localhost, or staging or obvious test domains (stuff like "https://testing-this-ot.vercel.app";, we're down to ~300. My hand-wavey guess is the majority of these will be served by the non-cookie SAA stuff we shipped, or have already resolved their need to use the OT.
Will this be the last renewal? Hard to predict the future, but if we do find ourselves in that bucket I would like to craft it in such a way to continue to narrow the funnel further than we are right now, especially to avoid timeline contention and side-channels with 3PCD.
* We will respond to this intent with a link to a blog post once the renewal process is in place.
