Cairo is not contained in the release candidate.
Correct. Cairo hasn't been included at all in 2.8.0. See https://www.xquartz.org/releases/XQuartz-2.8.0_beta1.html
On High Sierra, where I had not installed RC3, these files were left intact with RC2:
pete 278 /\ l /opt/X11/lib/libc*

-rwxr-xr-x 1 pete wheel 2006608 2016-10-29 09:59 /opt/X11/lib/libcairo.2.dylib
lrwxr-xr-x 1 alpha wheel 16 2018-03-30 22:27 /opt/X11/lib/libcairo.dylib -> libcairo.2.dylib
With RC3 installed they are gone now.
