Hi there, I'm the developer of this port.
I did use AI to assist me in development and I'm not shy about admitting that. This was still a hands-on effort that took well over 40 hours of development time spread over a couple months. Much like other development tools, AI certainly sped up my development process and allowed to ship something in a couple of months using my free time.
AI is a tool and it isn't going anywhere, I've posted my thoughts about AI extensively in the PowerPC community. I don't proactively volunteer or plaster my readmes with notes about AI because it doesn't really matter.
Speaking for me personally I have no problem using tools in my toolbelt to solve problems faster in my limited free time.
