Physics in general is the study of quantities, some of which are frame-
dependent and some of which are not.

That's a poor defense of Einstein's oxymoronic emphasis.

According to Klein, Weyl and Wikipedia, geometry is the study of
invariants.

"Every geometry is defined by a group of transformations, and the goal
of every geometry is to study invariants of this group." Klein,
Erlanger Program.

"Each type of geometry is the study of the invariants of a group of
transformations; that is, the symmetry transformation of some chosen
space." Stewart and Golubitsky 1993, p. 44.

"A geometry is defined by a group of transformations, and investigates
everything that is invariant under the transformations of this given
group." Weyl 1952, p. 133.

"The geometry of Minkowski space is defined by the Poincaré group."

Don't you believe in the spacetime geometry model that is so popular
today?
