I would imagine there are a lot of "small nice to haves" that people submit because they are frustrated about the mere complexity of submitting changes. Minor things that involve a lot of complexity merely in terms of changing some config or some default etc. Something where there is a significant probability of it being wrong but also a high probability of someone who knows the project being able to quickly see if it's ok or not.
i.e. imagine a change that is literally a small diff, that is easy to describe as a mere user and not a developer, and that requires quite a lot of deep understanding merely to submit as a PR (build the project! run the tests! write the template for the PR!).
Really a lot of this stuff ends up being a kind of failure mode of various projects that we all fall into at some point where "config" is in the code and what could be a simple change and test required a lot of friction.
Obviously not all submissions are going to be like this but I think I've tried a few little ones like that where I would normally just leave whatever annoyance I have alone but think "hey maybe it's 10 min faff with AI and a PR".
The structure of the project incentives kind of creates this. Increasing cost to contribution is a valid strategy of course, but from a holistic project point of view it is not always a good one especially assuming you are not dealing with adversarial contributors but only slightly incompetent ones.
