I remove the wide angle when I have to shoot a macro and replace it with a diopter
If the weight or size of the lens is such that I can't complete the operation safely with one hand then I am not comfortable in currents or difficult conditions
Taking a pouch in and out a pocket requires two hands whilst using a lens caddy only requires one
Still the effort of unscrewing the lens, screwing it on the caddy unscrewing the diopter and screwing this on the port means 4 operations on threads for a single shot the lens being heavy doesn't help either
Compare this with taking lenses on and off a bayonet mount and them you can see you will miss less photo opportunities
