If I remember right, clearing it for one site didn't help because clearing "login.paypal.com" cookies didn't clear "some-other-thing.paypal.com" or "www.paypal.com". They seem to use www.paypal.com for everything now.
Google for: "paypal Your browser sent a request that this server could not understand" for one example
Or "paypal your last action could not be completed" for another.

Right, but that's not a problem that this particular change is going to do anything about. Previously, you had to find all the different paypal domains and whack their cookies and now you have to do the same. The functionality you can't do in the Preferences window now (but you can in DevTools) is find a single cookie in a single site and whack that one. That's the one that would be Daily WTFy.
This will be harder, especially where you need to clear cookies on different domains like a login page, saml page, account page, etc.
