Interesting points, but mostly disagree because you can adjust how you make the dev log, there are pros and cons.
I can't remember shit, dev logs are part of the process and help with finalizing a vision. Asking for feedback is valid, it's still your vision.
You can make this content and the game at the same time. There is nothing wrong with them, but there are benefits to focusing on your internal values and just not publishing your logs for all to pick apart.
