Ahh! Author here. Thanks for posting! In case anyone wants to share in my frustration, I also wrote a blog post about this.

The prompt I use to tell the LLM what to fix: https://github.com/zachahn/vomit/blob/main/internal/config/s...

Wasn't received too well on Lobsters haha, wrote a small extra blurb about it there: https://lobste.rs/s/juekuk/how_fix_claude_5_s_token_vomit

I can't really comment on GitHub, but Rails supports composite primary keys as of Rails 7.1, the latest released version [1].

About modularity, there are projects like Mongoid which can completely replace ActiveRecord. And there are plugins for the view layer, like "jbuilder" and "haml", and we can bypass the view layer completely by generating/sending data inside controller actions. But fair, I don't know if we can completely replace the view and controller layers.

I know I'm missing your larger point about architecture! I don't have so much to say, but I agree I've definitely worked on some hard-to-maintain systems. I wonder if that's an inevitability of Rails or an inevitability of software systems—though I'm sure there are exceptional codebases out there somewhere!
