Nothing wrong with a collection of cameras on the shelf. it is as much a part of one's history as that photo framed on the wall.
The mistake with thinking that a minimum amount of photo gear clears the mind, is that it is not the amount it how you use it. Different cameras, different formats, different lenses do different things, the problem comes when one tries to do all at the same time. Just bring on each adventure what you know you will use and if next time has different needs bring the stuff that is best to capture those images. They are just tools sometimes you need a table saw, sometimes a jig saw and some times a chain saw.
