there is SOOOOO much to do after the main quest, it would be cool to get a sword or some armour. The only way it would be not useful is if you stop playing after MQ and not explore or do any side quests.
It would have been good if they rounded it up like Oblivion. Firstly they give you a finishing video with a voice-over to basically round off the story and then reward you some unique item as a trophy. The ending of a main quest should be something special and not just end like a regular guild one. Even the ending of the College of Winterhold questline felt more satisfying.
