[postgis-devel] Precision Reduction?

One of the "new" GEOS 3.9 features is that

GEOSGeom_setPrecision

actually backs onto the OverlayNG precision reducer, so you can get valid precision reduced geometries out of it.

Currently, nothing in PostGIS exposes this functionality (because prior to this the precision reducer in GEOS wasn't really any smarter than our own snap to grid). 

Should we be exposing this?

Under what name?
