What is the physical significance of gauge symmetries?

Many discussions in the philosophy of physics.  Dis-analogy of gauge symmetries to global symmetries via Galilean ship constructions.  Greaves and Wallace object. They claim there can be physical symmetries in terms of asymptotic symmetries, i.e. there can be Galilean ship constructions.

Notes that asymptotic symmetries play an important role in holographic duality.

Rovelli’s (very) recent paper claims gauge d.o.f. contain information about possible couplings between physical symmetries.
