Some industries(Like architecture) use 3D software in order to export drawings which are coloured into for presentation purposes.
Fusion has no control over the maximum thickness of line-weights which would be very helpful. In general exporting with line weights in Fusion generates a very bad quality drawing.
It could also be helpful if the user could set the rate over which a line gets thicker across space. For instance, +.25mm thickness per 80mm of distance from the camera; with a maximum thickness of 1.5mm line weight.
Hope my comment was clear and other people find the issue as important as I do!
