Background stories are not a source of free advantages, and that includes social contacts, rich families, and noble titles.
I actually dont have a problem allowing that . A serious player making a little extra effort should be rewarded . Possibly some other players will follow his lead .

It would be awesome if players did that for no reward but this is the Real DND world and everyone expects XP , gold or magic goodies for their participation .

Someone dreams of that perfect magic goodie for his hero , this could be just the loophole he needs .
