OK, fwiw, the reason translate() creates a copy is because the use of copy=True in Shape._apply_transform(): https://github.com/CadQuery/cadquery/blob/c9d3f1e693d8d3b59054c8f10027c46a55342b22/cadquery/occ_impl/shapes.py#L846.  I tried setting it to False and my original example passes.
Thanks.  Playing around a bit more, it seems like translate() makes the underlying TShapes unequal, but Shape.moved() preserves TShape.  This returns true, which could be useful:

x1 = cq.Workplane().box(3,4,5)
x2 = cq.Workplane(x1.findSolid().moved(cq.Location(cq.Vector(1,2,3),cq.Vector(4,5,6),7)))

f1 = x1.faces(">Z").val()
f2 = x2.faces(">Z").val()

f1.wrapped.TShape() == f2.wrapped.TShape()   <=== TRUE
