-------------------------+---------------------------
 To do the ST_PointOnSurface() operation without the need for a cast to
 Geometry.

 I would not use an `ST_` prefixed functions because that prefix under
 topology is used to distinguish ISO SQL/MM specified signatures from the
 others, and SQL/MM does NOT know about TopoGeometry at all.

 But we could be nice and use the ST prefix like we actually already do
 with ST_Simplify(TopoGeometry) -
 https://postgis.net/docs/TP_ST_Simplify.html

 See also #4861 which would likely be a basic component of this, for Areal
 TopoGeometry objects
