I have no official information either, but I always mask headers greater than the version of kernel I'm using right now, just because it feels wrong to me. there are about two dozen packages on my system that depend on os-headers or linux-headers, so I don't get comfort from "basically only glibc cares" statements. But maybe I'm just worrying for no good reason. :)
