This is probably more relevant for one of the species with no obvious ID features, but I'd note that we've just lost one of the truly great English bird-names as the IOC has lumped Perplexing Scrubwren. So I'd quite like to have a Perplexing Warbler to make up for that.
Admittedly, I'd struggle to make a case for "perplexing" being a unique ID feature for a warbler.
