Solution could be:
Create a polygonlist not refering to vertex-indexnumbers but real vertex data. Create new vertexlist based on polygonlist. Create a cross-reference-list to original vertex-list. Save obj-file. Save cross-reference-list with the same name.
On load: Load obj-file. Load cross-reference-list. Use cross-reference-list to translate loaded index-positions to real vertex positions.
As I said: error-prone, and, allmost all modern modelers are able to handle the situation if properly configured.
