CHIPS is similar to the state partitioning mechanism implemented by Firefox. The difference is that state partitioning partitions cookie storage and retrieval into separate cookie jars for each top-level site, without a mechanism to allow opt-in to third-party cookies if desired. As browsers start to phase out third-party cookie usage, there are still valid, non-tracking uses of third-party cookies that need to be permitted while developers begin to handle this change.
so this adds a setting to allow a site access to shared 3rd party cookies, when the site supports the feature?
my impression was that it was impossible already, because there was effectively a different cookie storage for every site

You can embed bits of a website in other websites, that’s how 3rd party cookies exist
