When there's a programming language in the project name and it's not a library, it's not a good sign. It means that there was nothing interesting worth mentioning.
In general you are right, but as the readme says, this project was an experiment to try out the stack. The intended consumer of the repo is probably not someone who wants to run yet-another-chatgpt-clone, but someone who wants to poke at the code, in which case the stack is the most relevant information!
