It is possible that some projects could benefit from triage volunteers?

There are plenty of open source projects where it is difficult to get up to speed with the intricacies of the architecture that limits the ability of talented coders to contribute on a small scale.

There might be merit in having a channel for AI contributions that casual helpers can assess to see if they pass a minimum threshold before passing on to a project maintainer to assess how the change works within the context of the overall architecture.

It would also be fascinating to see how good an AI would be at assessing the quality of a set of AI generated changes absent the instructions that generated them. They may not be able to clearly identify whether the change would work, but can they at least rank a collection of submissions to select the ones most worth looking at?

At the very least the pile of PRs count as data of things that people wanted to do, even if the code was completely unusable, placing it into a pile somewhere might be minable for the intentions of erstwhile contributors.
