For many CLIs and developer tooling, principled decisions need to reign. Accepting the unquantifiability of usage in a principled product is often difficult for those that are not the target demographic, but for developer tools specifically (be they programming languages, CLIs, APIs, SDKs, etc), cohesion and common sense are usually enough. It also seems real hard for product teams to accept the value of the status quo with these existing, heavily used tools.
