> One point I missed when I saw your patch first time, but I realised during the discussion:
> Up to 4.9, GCC was numbered with 3 digits, we had 4.8.0, 4.8.1, ... 4.8.5, 4.9.0, 4.9.1, .... 4.9.4

One line below in Documentation/process/changes.rst,
Clang/LLVM (optional) 10.0.1 clang --version
Clang 10.0.1 is a bug fix release of Clang 10
I do not think GCC 5.2 is strange when we
want to exclude the initial release of GCC 5.
