I love this. For a couple of reasons.

1/I often discover new things and have new thoughts and ideas along the way of an implementation which hadn't presented themselves previously.

2/I think it's a great way to avoid overthinking a feature or arguing too much for or against it. If nearing a majority consensus (with oneself or team) and there is time to spare, add it to Version 2 -- advantages being point #1 above, and having it prepared should it be deemed worthy to be merged to Version 1. I've heard that having features in the chamber ready to release is something big corps commonly do.
