This is one of the biggest issues in software development: So few projects are willing to admit that they are finished. I can probably count on one hand how many software products I use every day that actually get better (or stay the same) on update. The vast majority of them peaked somewhere around v1.0, and are just getting worse every time the developer touches them.

I can understand the incentives for professional software. If you admit the software is done then management will question why they need you anymore.

For OSS it’s more psychological: admitting you’re feature complete is cutting off the dopamine hit of building new things.
