The only reason to add the FFT code/mode would be to allow the use of a nanoVNA as a narrow band spectrum analyzer using the CH1 input with the disclaimer there is NO mirror suppression so

nanoVNA use IF for measure data (CH0 reference, reflection, and CH1) Default not allow see how it work. I add some code from Eric SA-FFT sources, and can better see ADC work quality (screenshots) This

Re: Cheap preamps
One problem, too, is that the 1/f knee for those GaAs or InGaP MMICs can be at a fairly high frequency (10s or 100s of kHz). You typically won't find that in the mfr data sheet. The parts are cheap,
