Writers are notorious for wanting to change practically everything once they see their work set in type. Maybe that's why convention publishers will charge the author if alterations on the galleys or page are proofs are. This serves as a deter to rewriting the whole manuscript. You must give yourself a cut off limit after which you will consciously try to leave things as you have written them, if not you can spent your lifetime rewriting and never get your book into print.
Retain your original manuscript, and store it in a fireproof box or bank safe deposit box. I won't go so far as to say that publishers are careless, but they are human, just like he mail carrier. As long as you provide a legible, there is no reason to submit and original to a publisher or to a printer because it can be misplace
