Separate viewport background colors for wireframe and solid modes

The default dark background of the viewport is great for editing in solid mode, the grey (or colored) objects stand out clearly against it. But in wireframe mode, the black lines are harder to see. The shading pop over allows you to set the background to 'viewport' and select a custom (let's say brighter) color, but that color will then also be used for solid mode as the setting seems to be shared between the two modes.

Wouldn't it be better if wireframe and solid mode had their own separate viewport background color swatches?
