A maintainer explains why they no longer want pull requests from contributors, citing security concerns and coordination challenges. With LLMs generating code faster than humans can review, the traditional PR model no longer makes sense when maintainers can implement changes themselves with AI assistance and maintain complete control over the codebase.

The maintainer sees source code as less "source" and more "code"—an intermediate layer between ideas and instructions. LLMs enable faster iteration than coordinating with human contributors, especially across time zones, while reducing the risk of malicious code that comes from unknown contributors.

Rather than submitting PRs, contributors can help by providing feedback, discussing ideas, reporting bugs, sharing prototypes with prompts, reviewing code, and forking the project for custom implementations. The maintainer encourages developers to make changes independently without seeking permission, as this approach saves everyone time while accelerating innovation.
