Subpixel antialiasing is kind of overrated anyway. On screens that are low enough DPI to benefit from it, it can cause color fringing (especially for people with astigmatism) that is worse than the blur from grayscale antialiasing.

I disagree: I am not susceptible to colour fringing, and I can tell if subpixel rendering is on or off on 24" 4k screens (~190 ppi) at a regular or even further viewing distance (~70cm/27") — I specifically got that display hoping for subpixel rendering to be turned off.

Haven't tried Apple's big "retina" screens but considering they are ~215 ppi, pretty confident 10% increase in PPI wouldn't make a difference that subpixel rendering does. Laptop screens have higher resolution, but haven't really paid attention to whether M1 Air 13" or 4K 14" X1 Carbon work for me without subpixel rendering (I prefer to be docked).

Before anyone jumps on "you've got incredible vision": I wear either glasses or contacts, and with that my vision corrects to better than 20/20 — slightly lower correction induces headaches for me. Without glasses, I'd probably be happy with 640x480 on 32" so they are kind of a must. :)

On medium-DPI screens, I find that subpixel antialiasing make fonts significantly less blurry than grayscale antialiasing without causing obvious color fringing. On actual low-DPI screens, bitmap fonts are IMO the only really usable option. (YMMV, but I have mild astigmatism and use glasses.)
