Hi Steve, sorry yes that last part about SimplifyCrv and FitCrv was about Rhino and not MoI (screenshots there were Rhino screenshots).

Right now Offset is oriented towards getting an accurate (and as a side effect heavier) result, when I get a chance to spend some time on that, it should be possible for me to tune that up to reduce the density at least somewhat. But it is a bit of a tricky thing to do it and maintain a good amount of accuracy.

Eventually there will be some commands in MoI for reconstructing a curve, like Rhino's FitCrv or Rebuild commands, but those are not present in MoI quite yet though.
