JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open!
Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software?

Maybe the next generation will set its sights on solving systemic problems instead of “My burrito is at a restaurant, but I’m all cozy here so, can a guy with a medical degree from another country bring it to me.” We’ve got that covered, and then some.

Liking Claude Code even more: I'm slow adopter, but today got into tool-making; asked Claude to write a script to find all `jackson-databind` issues with 5 or more upvotes.
1-shotted nice Python script that called Github API and it... Just Worked.
Old News I know. But I'm getting there.

/5 Now. Members of the United States military are not obligated to follow unlawful orders. This is baked into the law; it’s not subject to dispute. A soldier refusing an order will have to establish the order was ”manifestly unlawful.”

Had forgotten approx. size of Jackson codebase, checked. Somewhat smaller than I thought. FWTW, LoCs:
1. `jackson-core` (streaming JSON read/write): ~60k
2. `jackson-databind` (Java Object mapping): ~135k
3. `jackson-annotations`: ~6k
(2.20.0 and 3.0.0 very similar).
So abt 200k of Java for core
1. `jackson-core` (streaming JSON read/write): ~60k
2. `jackson-databind` (Java Object mapping): ~135k
3. `jackson-annotations`: ~6k

Why do people start with a possibly good straight-forward idea, but then complify specification and fux0r it up?
See github.com/toon-format/... -- smells like YAMLng. :-p
