It allows to control the spacing vs width (10%% fill vs a bit less) The 'enforce 100% fill volume' is also adjusted to take that into account Note that if you're using multiple extruders/filament everywhere (and spacing setting for width setting), the result may be a bit unexpected, as the gui can't display all the interactions, also some features (like support) may revert to default overlap value, if printed with multiple filaments. supermerill/SuperSlicer#1590
