We have softselections on Face mode on editpoly.
But when using Extrude/bevels/insets/andothers this softselection has no meaning, a selection of "1" intensity will be full extruded, a selection of "0.95" intensity will simply not extruded.
For dynamic effects will be cool if at the moment of polygons extrusions, or insets we drive the value of extrusions or insets with the value of the softselection, so we can have gradient effects and not simply a boolean on/off.
