I've never really needed it! I've been doing aural zero beating for so many 
years (46 now) that I can usually get within a few tens of Hz even without 
hearing the sidetone, and within 10 Hz when using the sidetone.

For those who haven't developed to knack, or who just like bells (err, 
LEDs) 'n whistles, the CW Tuning Indicator is a nice adjunct.
