Hi Petr, yes there are a couple of different techniques that I can use to do this.

For improving lofting it is a little trickier, since it has to be done in a synchronized way to a whole set of curves, not just one. For instance if one curve needs to have a point inserted, the other curves also need to insert that point so they stay synchronized and can more easily create a simple surface when they are combined through lofting.

Yup, this would be the rebuild command, several people have already requested it. It will definitely happen at some point but I'm not sure when yet. Ideally this command would allow you to tell it either a number of control points or a tolerance value and it would create a new curve that followed the shape of the old one.

A slightly different version of this is actually already happening in the Freeform/Sketch command - if you turn on control points of a sketched curve you should see that they are pretty sparse.
