Yes - which has the advantage that you can select different behaviours
rather than distributions having to build with HZ=1000 either for
compatibility or responsiveness can still allow users to drop to a lower
HZ value if doing stuff like HPC.

Basically it removes the need to argue about it at build time and lets
the user decide.
