Try-ing to supporto esri arcgis will introduce other and bigger problems.

We have many trouble due to the convention of esri for the hole that
are touching the boundary of a polygon.

The esri product will trasform this in a not OGC compatibile structure.
That on a OGC system is defined Invalid.
So when a dataset with hole is touched from a esri arcgis it could
became invalid for OGC.

This is so a problem for us that we fund a change to postgis to have a
ST_IsValid with a flag for compatibily with esri gemetries.

QGIS is absolutely unuseful try to follow Arcgis if QGIS himself also
don't support this different structure of polygons with hole on
