While the ICCCM mandates the use of this, it's not necessary under a composited environment from my understanding, and it's a flat out no-op under XWayland. Looking at the other rootless servers like Xwin/Xquartz, it seems that they contain code for colormap emulation, but they're actually never used -- a bug prevents the code from ever being called. Given that it's been this way since 2003, I'm going to hazard a guess that not many apps using colormaps. Kill them off.
