Fedora definitely has cake in its kernel, and eventually these kernel things get into RHEL and Centos.
FYI, my router/gateway to the Internet at home is based on Fedora Server Edition (Fedora 33, as I wait a little to upgrade my router/gateway after a new edition is released, as Fedora 34 was just put out). I've been running cake in it for years now, and it has given me no trouble. I started with it being added by use of DKMS when cake wasn't in the standard kernel yet. I had a glitch when it made it into the standard kernel and DKMS got confused and I had to figure out why the cake config wasn't working.
Now Fedora's not quite just an early availability for RHEL, but for kernel functionality it has been. I understand why for Enterprise use, RHEL is conservative about tracking the leading edge.
