Exit Objectives, Are they worth It?

[Grrr]

According to the Manual;

"An objective hex worth "0" (or "?" for the enemy with Fog of War active) at a scenario's start, is an Exit Objective. This objective earns Victory Points for its side whenever a friendly unit is removed from the map at its hex. Exit Objectives are found at a map's edge. To exit a unit, move it onto an Exit Objective and with it selected use the menu options Command and Remove From Map. The unit will permanently exit the game and the value of the Exit Objective will increase. Exit Objectives never change ownership but the presence of the enemy will deny its use."

Now I've rarely had the opprotunity to reach and use exit objectives but in some games and or scenarios, the decision to use the exit objectives seems to me to be problematic. The Bulge is one game that comes right to mind. If, as the Germans, you reach and Cross the Meuse River, most likely around the 20th of December, are the points gained by using the exit objectives worth the lose of valuable combat strength?
Is there anybody who has removed several divisions by way of the exit objectives and still won the scenario? I would appreciate any insight anyone has on the subject.
