My prediction is that many new contributors would complain loudly. Some existing contributors would sympathize.

It’s I think a normal evolution of a social norm. There will be a period of competing values.

people would use LLMS for those summaries, defeating the purpose. You can already see it in PRs in companies where LLM code is pushed.

Explain, in at most 300 characters, why we should merge your change, or at least why we should invest the time to read a longer explanation (somethings things ARE complex) would simply become a prompt.

The solution, of course, is to use the best available LLMs as the first line of defense against slop contributions. But if the project maintainers have issued a sweeping fatwa prohibiting an entire class of useful tools, that option along with many others is off the table.
