That is not how it works. Most projects have a hard date to get that Gold Master ready by for shipping so they can go print discs/carts. If you've ever played anything on PS2 or earlier, then you should be fully aware of the bugs you find in even the best games. The Day-One patch is so developers can keep working right up until the actual launch date to get bugs squashed.

That is not the case for entire features, however, that's just bad planning.
