Gmsh export to .su2 mesh

I am currently using a python script to build a mesh around an airfoil. However, once the msh is completed and it is time to export from Gmsh to .su2 mesh format one error occurs go wrong. The mesh file that is produced for SU2 the .su2 file has points which are used in the process of building the geometry. I have tried to created physical groups and then export without hiting save all but this has been of no use. The current .geo file is the following:

It is a bit odd and I don't know how to resolve the issue in a standard way, because those entities (say, Point 80 at (-30,0,0)) appears even in the native GMSH mesh format. The "building points" are present in the msh v4 format which was relatively recently introduced. And while I am sure there is a way to turn those off from being exported, I don't know exactly how.

However, I found a workaround. Alternatively to the standard workflow, you can use msh v2 legacy format. In this case, I see a clean mesh without extra points:

Then, you can use this mshv2 file to convert it to any other mesh format of your choice.

To obtain the mshv2, I use command line:

/Applications/Gmsh.app/Contents/MacOS/gmsh -2 -format msh2 test.geo 

If you are using Windows or GMSH binary installed any other fashion, adjust you path to GMSH executable.

While this answer does not satisfy me to 100%, it should offer at least a temporary workaround.
