Jiri is aware, and has been for some time, but upstream was trying to agree on which fix to use last I saw. Non rawhide kernels are typically the safer bet, though there have been rare cases where something needed to be added to the spec to make the kernel build with a new toolchain (gcc 10), and that spec change was not propagated down as that toolchain was never intended for the existing stable releases. I think with the new ark workflow, it will not be a problem.
