But who can gauge the sway of thine,
Which reaches high to heaven's dome,
And acts within the darksome mine?

Can never gauge the mighty strain,

To see at last beyond the dust and shade,
And face real foemen, strong and unafraid.

Point particle in general background fields and generalized equivalence principle
Recall a general proposition: if one has a nonlinear action ( ˜A[H ]) with inﬁnitesimal gauge invariance δH = Rε [H ], then the linearized action hP h is gauge invariant w.r.t. linearized inhomogeneous, h-independent gauge transformations given by gauge variation of the vacuum solution: δh = Rε [Hv ].

This is known as the ‘gauge invariance of gauge transformations’ and is a typical property of reducible gauge theories6 where the generators of gauge transformation are not all independent .
