Absolutely. I certainly understand Why it works the way it does. Especially when dealing with 3rd party modules, it's good to be explicit about which version of a submodule should be included. But having a setting that allows me to keep a submodule at HEAD at all times would certainly help me save quite a few keystrokes for my own internal libraries - most of which I quite regularly find myself crawling up the tree to add, commit, and push.
