This is commonplace for most people when they start working on a new project, including myself. And sometimes when you are rushing through to meet some deadline it slips through and you end up realizing a lot later. In order to tackle this, I've developed the habit of adding a middle layer in the code between the configuration (whether it be ENV variables or config files) and the actual application. So when you eventually have time or realize that you forgot about it, swapping/fixing it isn't an issue.
