Some time ago I made an abstraction "hey, most people in our company who use CloudFront don't care about all the implementation details, they just want some paths to be somewhat cached". I explained this idea to a coworker. It took a while, but he understood it. Two months later someone merged a PR that replaced my interface "I want this and this path cached" with a simple passthrough that exposes raw AWS interface. Same thing happened to S3 buckets where I noticed that most people just want "auto-delete files after X days either on or off".

I spent entire year trying to explain to my manager "most devs who create services want a simple deploy button". Instead, we tried to teach devs how our "infrastructure as a code" works so that they'd contribute. The effect was that only one guy engaged with us this way, and he always sent us AI-generated PRs, and every time he saw an error, he just copy-pasted it to ChatGPT without reading and then the answer back to me.

The project eventually shifted towards my original idea, but in an extremely painful way without any design at all. It's just a toolbox of completely random features glued together because one day manager says "no we don't need to support X" and two months later a Jira ticket "add support of X".
