Steven, would you mind to check if this is the feature we've discussed in the meeting? Thanks!

Yes this matches my expectations. You're able to exempt a specific third party from partitioning on all first parties by setting privacy.restrict3rdpartystorage.skip_list = *,example.com where * is the wildcard for any first party and example.com is the third-party origin.

I have two questions:

1. How do you exempt multiple first-party, third-party domain pairs? Is the csv just assumed to be pairs?
2. Is it possible to exempt the other way as well. E.g., example.com, * -- basically allowing us to say "don't partition anything on this site"

It's a semicolon-separated list of comma-spearated pairs.
Like this: "foo.com,bar.com;*,example.com".

2. Is it possible to exempt the other way as well. E.g., example.com, * -- basically allowing us to say "don't partition anything on this site"

Yes, this is possible, I'll update the patch.
