Correct; we have seen this already in the past (see e.g. gnulib-common.m4).

I think you are confusing version numbers here. What you state disagrees
with [1]. Also, I have Linux binaries [2]:

Nov 28  2019 clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04.tar.xz
Oct  8  2021 clang+llvm-13.0.0-x86_64-linux-gnu-ubuntu-20.04.tar.xz
