Using the RTC or HPET devices directly is necessary only if

What are those timer API's?
POSIX timers, interval timers, nanosleep(), usleep(), poll() timeout.
You'd need this only if you're using some audio application that hasn't
been updated for many years.
So this section has become deprecated?

Only if all applications actually have been updated.
Wasn't there some sequencer (Rosegarden? Muse?) that still uses RTC?
Can you imagine any reason why an app using /dev/rtc or /dev/hpet would
need write access, or would it be sufficient to do something like 0640
root:realtime ?
