Not really. Using the RTC or HPET devices directly is necessary only if

You'd need this only if you're using some audio application that hasn't
been updated for many years.

The risk was that handling interrupts at a frequency of 8 kHz would not
leave enough CPU time for applications. I doubt that you have any CPU
where this is actually the case.
