I've never observed this myself. If a new compiler warning is added to
gcc and if it produces warnings that are not useful for kernel code
usually Linus or someone else is quick to suppress that warning.

Another argument in favor of W=1 is that the formatting of kernel-doc
headers is checked only if W=1 is passed to make.
