Livre d'Or

Yes, that's true. I glossed over the fine detail a bit, I think people with Liberal or convert ancestries probably can get citizenship in Israel, but sometimes they get registered as non-Jewish, and that shouldn't matter but it can do. And there's this whole underlying assumption that "everybody" accepts Orthodox status definitions whereas the Orthodox don't accept non-O definitions, and therefore Orthodox status is superior (even if you otherwise disagree with Orthodox principles). I agree it's not directly about the Right of Return as such, but I do think that the thing of Anglo-Orthodoxy drifting rightwards is hugely influenced by Israeli status stuff.
