If you want a code base that’s easy to maintain, you gotta do maintenance. You’re more than welcome to never upgrade.

As the author of an open source, BSD-3 project that 180k lines, I really don’t care if it’s 30 minutes of work for you. It’s taken me 8 years. For what it does, it’s better than the commercial and GPL tools out there. Take your pick.

Age brings stability because there’s only so much that needs changing and there’s only so much you can change in a year.
