Idea: anything else we would want to warn about?

[Chrilleweb]

I’m looking for feedback on additional warnings that could be useful in dotenv-diff.

Are there any environment variable patterns, misconfigurations, or gotchas that you often see in real projects and would expect a tool like this to warn about?

This is a brainstorming / discussion issue — no code required.

Ideas, examples, and edge cases are very welcome.
