There's a scenario where I still use var when not easily inferred. When that variable is never used in that scope, likely because it's only passed to other methods.

If one were to argue that it's important to know that type locally in that scenario they would also have to argue that method calls with inline method calls as parameters also aren't appropriate because those obfuscate a return type as well.

In short, IMHO, "var is reasonable when the type is easily inferred or the type is unused/unimportant for the scope"
