I've seen "clean" codebases that conform to "best practices" which are even less decipherable than what you describe.

100KLoC sounds like paradise compared to the latest codebase I touched. Having the signal to noise ratio fluctuate wildly at every member & file is highly distracting. When the information is dense and consistent, you can drop into a flow state more easily.

Four character variable names might sound awful but they can have an advantage. It's a form of compression once you are adapted to it. It forces you to keep things simple. When we can write an entire novel for a variable name, we may be tempted to inflate the scope of a solution.

No comments is universally a feature. If I want justification for a section of code, I am going to check git blame, PRs, linked issues, email, project management system, etc. The only code comments I value less than those written by humans are those written by LLMs. It is beyond pointless to shit up a codebase with this stuff. You could just ask the LLM to give you a live interpretation of the current state of the code instead of risking something falling out of sync.
