Some of us are actually doing it. ;-)

That's because hunting in include/linux/ is much more fruitful -- it
decreases amount of code after preprocessing for everyone. Below are
allyesconfig on x86_64 results for some kernels:
$ wc ../*.i
79018171 229433654 2049266884 ../2.6.18.i
86568111 250674099 2245115663 ../2.6.19.i
85187296 247470579 2221334183 ../2.6.20.i <===
88645422 242396928 2234855428 ../2.6.21.i
93897302 257990496 2377174442 ../2.6.22.i
98381373 268683402 2486321956 ../2.6.23.i
E.g. we can have ~1.07% decrease in cpp output despite ~126000 lines
added between .19 and .20.

Yup! Provided they're compile-tested sufficiently well.

That way you'll never clean anything especially during merge window. ;-)
