No 'Most' or 'Every one' .. lots of touring is done on all sorts of pedals ..
I have done a bunch of Pack And ship Of people's bikes ..
some used Power grip straps and platform pedals , some Road Clipless , some MTB SPuDs
some just platform pedals & some toe clip and strap
I found My favorite for multi Month Long tours was Toe Clip and Strap pedals .. loosely 'strapped'
and shoes I fitted with comfortable Birkenstock Insoles with stiff arch supports .
and that Fit Loosely so the circulation to the toes was unrestricted , nerves not compressed
Clipless shoes have to be tighter so you release the cleat rather than Pull the foot out of the shoe.
I have some clipless shoes and Pedals too Just did not tour on them..
You have heard from all sides now, Make up your Own Mind. (?)
