I agree. I was contemplating a clock_init() or similar a way back for setting up clock trees early. We would have to move clock tree registration in front of the init_sched_clock() call in the init_early() handler in many cases since the rate often comes from the clock framework, but this is indeed where it belongs. So a clear ACK for this approach.
