Recently I have been doing some OSINT on a web page and tried exactly what you are mentioning: check the origin of the web server behind CloudFlare. I tried anthropic's claude help, but it turned out to be impossible (at least for the two of us: me & claude).

* It would be very easy for Cloudflare to implement such a filter. *

What you are stating, the way I understand it, is that in order to implement your original idea (EU browser), one would need the second thing as well, which is force Claudeflare by EU regulations to expose the IP of the server behind a proxy? Maybe it would be easy to implement for Claudflare, but how would you otherwise convince them to do that?

Looks like a pretty big scope creep to me.
