Unenforceable - sure, but it's interesting and I see the logic. While LLMs are extremely useful, I find they homongenise things. Claude text is instantly identifiable and now all my co-workers presentations and docs sound like it. I'm sure that extra effort helps differentiate things (so many LLM generated sites look the same so not many people put in the effort).
A project without everyone putting the same filter between them and the work they submit might help a project evolve in interesting and different ways.
