Oof, this is quite new but now that kernel.org has LLVM binaries
available, I do not think this is an unreasonable ask, especially if it

One question: Is it worth dropping the mention about CC=clang for
clang-18 and older in Documentation/kbuild/llvm.rst? Maybe it is better
to leave it around for a bit just in case people read the newer
documentation while working on an older kernel?
