Yes, that makes sense.

So let us write down what kind of geometric calculation we use today in
PCB. Then we should write down what nice features are blocked because of
lack of other geometric calculation.

For example, I'd implement the rounding of polygons like this:



----------           to have something like this:      ---------------

/                                                                         )

/                                                                        /
