0023379: Exporting single point into STEP produces a compound with two points
As stated above, exporting a single point into STEP and then importing it from STEP again produces a compound containing two other compounds with a single point.
Other systems interpret the imported STEP file in a similar way (producing two points), so I guess this is a problem with export (rather than import).
Draw reproducer:

pload ALL
restore point.brep point
stepwrite 0 point point.step
stepread point.step a *
explode a_1
