Not sure anyone has much use for HPGL files anymore either. Printing
on plotters is petty-much dead.

The obvious one is DWG (more proprietary successor to DXF). Which is
somewhat supported by the libreDWG library. Although in most cases
where DWG is useful, DXF will still work, so it's not worth putting in
effort unless people come up with concrete example where it is needed.

There have been several times I'd have found an output to an actual 3D
format, as opposed to line-based formats, would be really handy. There
are lots of fancy tools for 3D work. This requires transforming our
lines into thin cyclinders and maybe the points into small spheres.

Then we can use things like webGL which opens up a lot of
possibilities like displaying directly in the browser.
