Not all eBPF programs are compile once, run everywhere.
RHEL 'updates' can mean different things. A patch release won't change kernel ABI. A minor release will. Writing a non-CORE eBPF program for, say RHEL 8.6, might break on RHEL 8.7. It's not advisable to update across minor releases without lots of testing. Most of the time, things 'just work' but RHEL is a very complex product with a specific support cycle, and laziness of users and 3rd party vendors is not their fault.
