I think SS work hardens also so any movement in it would make it more and more brittle. The hose pipe protection might be worth a thought. Would it risk trapping moisture next to the copper and promoting corrosion?
Almost all metals work harden, but 'work' in this context means plastic deformation, not a bit of elastic deflection. Unless you are frequently bending the tubing it will not work harden. Copper is rather better at this than stainless steel but it is a scenario that should never occur in a properly designed system.
And yes, our hoses and regulators are replaced at five year intervals.
