Do we really now have any use of COMPILE_TEST=y WERROR=y with `make W=1`?
To me it seems every CI just disabled it because it's impossible to
build a kernel anymore.

What is the roadmap of fixing this (to some extent)?

I remember that Lee spent a lot of time cleaning up W=1 cases. Maybe
he knows the state of affairs of this with -Werror enabled...
