Will this allow sending Cross-Domain messages?

[jcubic]

In one of the recent version of Chrome new feature was added storage partitioning, that don't allow cross-domian communication on not related domains (it only works for subdomains).

Found this repo in Storage Access API article on MDN. Link from a new article Saying goodbye to third-party cookies in 2024

Will this API allow sending Cross Domain messages (with localStorage storage event or Broadcast channel)?

Also, it's not clear how to submit the set. Should I create a PR for this repo and add a JSON file? If yes then it's not clear where to add those JSON files.

I need this for my Open Source project that stopped working in Chrome for not related domains jcubic/sysend.js#54

RWS integrates with the Storage Access API so the improvements being made as part of privacycg/storage-access#102 will benefit developers using RWS as well, there's no relaxation of cross-site storage / communication APIs from RWS otherwise.

Also, it's not clear how to submit the set. Should I create a PR for this repo and add a JSON file? If yes then it's not clear where to add those JSON files.

The full steps are at https://github.com/GoogleChrome/related-website-sets/blob/main/Getting-Started.md, you should edit the main related_website_sets.JSON file in your PR.

@jcubic Note that we are currently running an Origin Trial between Chrome 120-124 if you'd like to test out the use of Storage Access API (SAA) to re-gain access to cross-site communication via localStorage or Broadcast Channel; please see details here. If the sites in question are within the same RWS, your SAA invocation will be auto-granted in Chrome.

Ah, indeed. I missed the fact that you had provided feedback on the relevant repo. Thank you!
