Just a comment.

The versioning functionality lives in the GeoDatabase (ArcObjects) side and
not in ESRI's PostgreSQL ST_Geometry implementation. I don't think anyone
can claim with a straight face that "versioning support" would be an
advantage of ESRI's type over PostGIS' geometry (that would be incorrect).
ESRI's argument for creating their own geometry type on PostgreSQL was the
same as it was for them to create their own geometry type on Oracle vs
Oracle Spatial's own SDO_GEOMETRY.
