Brave and Firefox both do that. I dont know about Chromium based browsers in this regard, but Firefox's total cookie protection already isolates cookies per-site.
Both browsers' adblockers will block domains ID'd as trackers, so there are no cookies to delete from any domain I would want to.
The more I think about it, why do you need that feature? Firefox and uBlock block tracking domains (and therefore cookies), and uBlock can be configured to block any domain you want.
So if your use case is: "I need any site I visit that is not in a tracker list to have all of its cookies denied, but I don't want to block cookies through my browser or block the entire domain."
Then Privacy Badger does have one feature uBlock does not, and its that one. However, because its not recommendable to use two ad blockers at the same time (i.e. Privacy Badger + uBlock) (see my other comment), Privacy Badger is still obsolete.
If you need that edge case functionality, download Cookie AutoDelete
