Binary compatibility is a myth: if you actually need 100% binary compatibility, then you need the actual binary from Red Hat because neither Red Hat nor any other commercial distro offers reproducible builds. CentOS had to reverse engineer code drops from Red Hat just like Oracle or Amazon. Oracle will sell you a support contract claiming "binary compatibility" even when they are using a newer kernel than what's in RHEL. They are trying to make lives easier to collaborate with their frienemies who all maintain a RHEL clone. That means calling CentOS what it actually is: upstream of RHEL.
