That is not a good thing. RH frankenkernels can contain subtle breakage. E.g. the Go and Rust standard libraries needed to add workarounds because certain RH versions implemented copy_file_range in a manner that returns error codes inconsistent with the documented API because patches were only backported for some filesystems but not for others. These issues never occurred on mainline.

And for the same reasons that the affected users chose a "stable" and "supported" distro they were also unable to upgrade to one where the issue was fixed.
