What do you think of my patch as a prerequisite?
https://lore.kernel.org/linux-kbuild/20250503084145.1994176-1-masahiroy@xxxxxxxxxx/T/#u
Perhaps, can you implement this series more simply?

My idea is to touch a single include/generated/global-rebuild.h
rather than multiple files such as gcc-plugins-deps.h, integer-wrap.h, etc.

When the file is touched, the entire kernel source tree will be rebuilt.
This may rebuild more than needed (e.g. vdso) but I do not think
it is a big deal.
