FeatureCollectionTable throws exception for GeometryType.Envelope

FeatureCollecitonTable with GeometryType.Envelope throws exception, saying that Exception for type Envelope : Geodatabase geometry type not supported. I'm trying to create Feature with Geometrytype.Envelope. Attached are the json files for four Fields and spatial reference.

I'm using

FeatureCollecitonTable fcTable = new(fieldList, geometryType, spatialReference, false, false);

It is exactly what the error message says: Envelope is not a supported geometry type to store in an ESRI GeoDatabase. Use Polygon instead.

Supported types are:

Point—The geometry type will be point.
Multipoint—The geometry type will be multipoint.
Polygon—The geometry type will be polygon.
Polyline—The geometry type will be polyline.
Multipatch—The geometry type will be multipatch.

I know. I did the conversion to Polygon. Isn't it not consistent to have GeometryType.Envelope but not supporting in GeoDatabse? You could do it internally in Esri side.

Sure but historically there's never been envelope as a geometry type in the geodata. The envelope is a special case geometry mostly used to just determine extents of a geometry and as such is a "helper" type separate from the other types. In hindsight it probably shouldn't have inherited from Geometry to begin with.
