Is it ok, after the acceptance of initial version, will switch to waveform callbacks to enable

Please let me know.

Is there any documentation available for waveform callback? What scenarios we can use
Waveform callbacks compared to traditional one?

I just need to remove unused variable, that is a simple fix.
