Comment (by tvijlbrief):

 I agree, that would not only be clearer but we would also be actually
 simplifying these geometries.

 I wonder what the positive condition is, more than 1 sub-geometry or at
 least one with a curve?

 This error is generated somewhere in libgeos, so the cause and correct fix
 are upstream.
 My PR proposal is just a workaround.
