curve in PDF file seems to have a ton of unneeded points

I opened a PDF file up in some vector software and discovered that a simple curve had a ton of points, I was quite surprised by this since the shape should only need 7 points. Is there a reason Onshape seems to be exporting curves like this, or a way to export a "simplified" curve?
I have attached an Onshape PDF drawing with a few simple shapes (exported from this file).
The top circle has what I would expect, just four points.
The other curves have a huge number of points! This "fat blue line" is really a ton of points all highlighted from a window select. If I zoom way way in I eventually can see the individual points.
This is what I was expecting to see, just 7 points.
(I drew this as a circle and a rectangle and combined/merged them in the vector software Affinity Designer.)

We are sending PDF drawings to a laser cutter which is why I had noticed this in the first place. Sometimes not ideal with all those extra points. But I totally understand from Onshape's perspective that is probably not something you would suggest or expect a user to be doing with PDF drawings.
So if I export a DXF I need an intermediate step (i'm using Inkscape) to open the DXF and save as an SVG for the laser. Or if I export as PDF I have now discovered I can open it in Affinity Designer, do a Select All and run a "smooth curve" command that does a nice job of optimizing the nodes, and then save as PDF or SVG for the laser. I was, of course, just hoping avoid the intermediate step each time.
Maybe that produces nice nodes...
