Via fencing not supporting arcs and single line of vias

[CantBelieveThisWorks]

Hello,
my use case is to add via fencing along the contour of a PCB (I just select the edge.cut line). This works, but I have noticed two quirks:

1. The tool places vias along both sides of the line, unless for small values of offset. With offset 0 it fails to place any. I would expect to have the option to only place a single line of vias, while still retaining the offset functionality, to control the placement away from the edge. I understand this might be somewhat difficult, as it could be tricky to determine which row the user wants. Alternatively, I would already be very happy, if the vias could be in separate groups, depending on which side of the line they are placed. This would make it very easy to delete the unwanted vias.

2. When using arcs as part of the outer contour, vias are only placed along the straight sections. I would expect the vias to be placed along the rounded sections, as well. See attached image.

I also attached the minimal example used to create the above:

Thanks for your time!
