Comment(by gitai):

 The ticket is about ST_Distance, not about removing the implicit
 geometry::geography cast across the board... fact is that calling
 st_geogfunction(geom) is exactly what (unintentionally) happened to me due
 to function overloading. Point being is that there is no "hint" as to what
 ST_MakePoint returns as opposed to functions like ST_GeogFromText where
 its clear, I mean like what makes a point more special for geometry than
 geography? Now I'm not suggesting to rename ST_MakePoint to
 ST_MakeGeomPoint,which is what it really does, as this would probably be a
 breaking change, but at least enforce the type safety in ST_Distance in a
 consistent manner.. I don't understand how this can be classified as
 "enhancement" seems like as a small overlooked usability bug that's
 painful to spot especially for newcomers to postgis (like me :)
