Who are people? People in USA? Where I live it's frankly a positive if you're on a different base than github. SQLite seems to manage fine without github, so I'm not sure why you think Zig isn't going to be. That being said I don't necessarily disagree with your position on maturity, SQLite has an official github mirror after all. Even if you don't want to bother with that there are a lot of ways to write about it without calling people monkeys.

SQLite doesn’t really accept PRs[0], so I don’t think is comparable here. The SQLite model is great for their purposes but I doubt it’s suited to a community-based open contribution setup.
