This is without a doubt needed. Either that or a 3rd option that is a mix of the infill/cutting meshes that allows you to amend localised wall counts on a surface without creating a boundary thats the shape of the mesh.
The below example is with cutting mesh, with a wall count reduced to 2 for the lettering, but I then get an undesired box around the mesh.
As its a wall count, using infill mesh makes no difference.
