Do you not need to earth the switching plate to the back metal box as well??
I am using chrome switches and thought it were good practice to connect it
to the mounting box?

Or did it long enough ago that relying on the metallic conduit for earth

It still is an Acceptable Method, provided that all joints are screwed (no
slip couplers allowed) [543-03-06] and that the earth terminal of each
wiring accessory is connected to an earth terminal in the associated
mounting box via a separate wire [543-02-07].
