ok there is quite a lot to unpack here and I notice I should have added a lot more context in my first post.
re: AI use in development
First of all let me say: I'm not the AI police!
I'm not against AI per se and I use it myself occassionally.
Also in this day and age I actually assume that every developer is using it more or less,
so I'm not sure a general disclosure of using AI would be necessary.
This thread was in response to getting PRs where the author commented that they did not do the work, it was AI. I didn't mean to include "AI enhanced development" or letting AI review first to get pointers for your follow-up review which I think are reasonable approaches for developers, because at some point you check the output, run tests, try it out locally, etc.
re: Why did I open the issues and what is credit
When I started working on OpenRefine, I worked on "good first issues" and noticed there weren't too many and some lacked specifics. That's why I commented on some issues that they might be good for starters in the past and also started specifying some myself, and tests or refactoring in a "remote corner of the product" are actually perfect for this 
I put credit in quotes and yes a "thank you" or this green point thing on your github profile would qualify, but in a broader sense I meant it as "every psychological concept that gets you motivated to work on open source in your free time", so in this case it would be helping out new devs or juniors to get started with "good first issues", that's why I tried to be thorough in my review and explain concepts to improve code quality (I had not intention to work on them myself).
re: community and AI
I did use my personal experience as a vehicle to open this conversation but I know that my frustration stems from my ideals/expectations clashing with the real world (which is my "problem" to deal with).
What I'm interested in the context of this community:
- is there a way we (I) can create and maintain "good first issues" and make them less attractive to AI-only-users so that the repo stays welcoming to beginners?
I started experimenting with putting "secret" prompts into issues, but when I used ChatGPT it ignored them, so that was unsuccessful. I'm also in favor of enforcing the PR template more (helps in reviewing generally) and in front end issues asking for before/after images where appropriate.
Also if you noted other issues or benefits arising from AI use, feel free to share.
P.S.
Btw I noticed that I came into the code reviews like Kramer into Seinfeld's apartment which was kind of awkward but I was considering alternatives and thought, if I dont say anything then the only thing I could do afterwards would be to re-open the issue or do it myself, so that was the best course of action for me. If you (@tfmorris or @Rory) disagree or have other preferences, please let me know!
Also I'm not opposed to move ahead with the PRs, they both lgtm so if there are no other objections they can be accepted.
