With SQL, when you modify an object, that object is now out there to be used or tweaked by other developers. Committing it is really just a statement of, I'm done working with this object and here's what I've done.

We have the problem of not committing objects as timely as we should. We make a modification and go our way until we realize a week later, we forgot to commit. So we commit, but the date time stamp of the commit is not helpful. That is just when the developer remembered.

I think it would be much, much more useful to know "when was this object changed". Maybe we don't know why it was changed or by whom since the commit is pending, but if we can at least know when and what, we can figure out the who and why.
