They work great for RF because it's relatively easy to construct a
hi-Q bandpass to get rid of all the harmonics. Ideal or no, a diode
mixer is just turing the signal on, and off. No linearity, no "in
between" - and a "perfect" diode would just make things worse.

A diode mixer works basically like an AND gate - so, seems to me it
might work great if you want to "multiply" using a SQUARE WAVE
carrier, but useless for most anything else "musical."
