I agree about some stands not having room for pedals, as I use them all the time. However, there are many that don't.

I come from an organ background, using my feet frequently on bass pedals or expression, in the case of a B3. As far as my other boards, I use a sustain pedal for piano and guitar, always a volume pedal, momentary switch for vocal harmony. and a 6 switch pedal for many functions.

I may be old fashioned, but I don't see how some, at least, are not necessary.
