> The LLM can a priori test on all possible software and hardware environments, test all possible edge cases for deployment, get feedback from millions of eyes on the project explicitly or implicitly via bug reports and usage, find good general case use features given the massive amounts of data gathered through the community of where the project needs to go next, etc?

Even if that's the ideal (and a very expensive one in terms of time and resources), I really don't think it accurately describes the maintainers of the very long tail of small open-source projects, especially those simple enough for the relevant features to be copied into a few files' worth of code.

Like, sure, projects like Linux, LLVM, Git, or the popular databases may fit that description, but people aren't trying to vendor those via LLMs (or so I hope). And in any case, if the project presently fulfills a user's specific use case, then it "going somewhere next" may well be viewed as a persistent risk.
