Wireframe mode being truly wireframe

Here you can see two cubes, partially overlapping each other. When I set viewport rendering to wireframe, I expect only edges to be rendered, not faces. And this is true until two faces overlap - then I experience z-fighting. Which leads to the conclusion that wireframe mode is not quite wireframe in fact...

There are specific cases, like hard surface modelling or working with multiple layers of maps etc. when you DO need overlapping faces, even though it is not generally recommended for modelling.

I wish I could avoid z-fighting in wireframe mode and have ONLY edges rendered in viewport, as it happens in many other programs.
