This is exactly it. The chunking of chapters and verses was so monks could verify their copies. Imagine a monastery, with 100 scholars who are tasked with copying the entire bible, with duplicates. The best way to verify that it was copied correctly is to do spot-checks where the source and transcribed documents are compared on certain chapters and verses. At this point, I don't think it's necessary to split them up for making copies. That said, a lot of churches have integrated chapter/verse look ups as part of their service/sermons/bible studies, so it would be very difficult to remove them now.
