So, the claim is that RHEL has broken packaging which doesn't reflect ABI changes, and somehow that means you have to reverse engineer its build mechanism from srpms to accommodate it being non-deterministic somehow? Care to give an example? I don't remember ever seeing one. (Of course package maintainers for EPEL, for instance, should use abipkgdiff. I don't remember what the status of automating that is in Fedora.)
