As someone who doesn't do this as much as I should, I agree. On projects that are well covered with tests, I find I'm less afraid to pick it back up again and start working on it, because I know there is less chance of some missing context I had in my head months ago and now is forgotten and my change will break the app. Most of my small projects have automated deploys using ansible, not because I couldn't do the deploy manually (in most cases it's ssh to the server, git pull, run migrations, collect static, restart the server), but because with ansible I don't need to remember the manual steps. I am sorely lacking in the documentation area tho :-) Your post prompted me to try to improve there, as I can definitely see the benefit.
