P: Photoshop 26.10 Selective Color UI Changed

So... one of the best Photoshop tools I've used for decades for color correction has been replaced overnight by a duplicate of "Color Balance." I can't simply no longer correct individual colors as I did intuitively before. Why has a tool that worked perfectly been destroyed? The change has been so disastrous and counterintuitive that I can only think it's a silly programming error!
