The fact is, most people can't write bug free code, that is also maintainable. It's a skill that takes years to hone. Even someone that is smart enough to understand all possible code paths and can prove it is bug free, doesn't automatically mean the code is written in a way that is easy to maintain.

Also, open source goes both ways. Anyone can submit, but maintainers can deny. Their project, their right.

Please remember, the bar has been set this high by successful projects.

One of the reasons Linux became the world's most used OS kernel was because of the high standard Linus maintained for his project. (Not saying I agree with his colorful word choices, but in my opinion most of the time he was 100% right about the PRs.)

That's why he calls himself benevolent dictator for life. The high standards must be maintained for the project to continue to be successful.
