Comment 2 for bug 1827038

That would also help, yes. Zone-like filling would be nice because it would minimize the narrower part length while maximizing its width, without need to think or define how wide exactly it can be.

Maybe it could also allow some kind of zone replacement: draw a wide track with highlight collisions/allow DRC violations. Select the track, change the minimum width.

Certainly this wouldn't be easy to implement. Interacting with DRC rules and interactive routing would be difficult.
