Actually it's not a subset. Even if the app is open source, what you gain from this error is: username, installation path, resource limits. All of those add something you don't know from the code itself. All can be useful when trying (respectively) injections / bruteforce auth, path traversal / secrets access, denial of service.

Also line numbers can help you identify the deployed version.

Also optional table prefixes which are deployment-specific.
