Color subpixel font hinting is on its way out. Windows 8 and 10 stopped using it for UWP (including the start menu / start screen); DirectWrite doesn't use it (font rendering in Edge and Firefox); Office 2013 doesn't use it. Certainly screen rotation (with windows tablets and phones) would involve a lot of inefficient re-rendering. But i think the official reason was that since the subpixel colouring effect depends on the background colour, it's hard to animate transitions efficiently. On a high-DPI screen, you'd be hard-pressed to notice the difference compared to greyscale hinting. Colour subpixels were a great hack, but high-DPI is the proper solution to this issue.
