Unless you're building an application that doesn't interact with external systems, chances are your job is never finished, even if you choose to consider it finished.

If you don't want to be a lifetime maintainer, then you have to transfer ownership to someone else or consider the project to have reached its end of support.

Consider an analogy to building houses, it may appear that the builder has finished their job since the house is fully constructed, but like any system, it requires maintenance for the entire duration of its lifetime.

Systems degrade over time without maintenance.
