I agree 100%, I think it's especially crazy to allow selecting 100, 250, 500, etc, whether at runtime or compile time. Might as well just go tickless.
How do you expect application developers to handle not being able to count on the resolution of nanosleep()? Currently they can at least assume 10ms on 2.4, 1ms on 2.6. Seems to me that if you are no longer guaranteed to be able to sleep 5ms on 2.6, you would just have to busywait. Is it me, or does that way lie madness?
