I understand what you mean. I haven't considered using AI for resource packs, and if I did, I would mark it as AI-generated, just like the game.
We shouldn't confuse one thing with the other; using AI isn't wrong, but not disclosing that you're using it is. Regarding the topic of this post, I don't plan to use AI. An art portfolio with AI-generated images is a farce; it doesn't make sense.
Those links you shared provide interesting information, thank you for them.
