My reason was simply to have fewer chemicals around. Since I develop film the same way each time and test film density regularity whatever added developing occurs is considered in the process. The developer is so diluted I can't imagine one would be able to see a significant difference. If anything you might get a boost in shadow detail. I generally rinse film for 1 minute before fixing. The advantages are I don't contaminate my precious fix and I don't have to worry about blistering effects from sodium carbonate in developers (I've actually had this problem but it really does occure), and I have fewer bottles around.
