I have always wondered, why can the lcc projection have a westo flag for a 
west orientation, but why can't tmerc have a south orientation?

The LCC West orientation is used for some rather old Greenland projections, 
whereas the tmerc South orientation is used today with respect to the 
South-African Hartebeesthoek datum.
