> Strengths: ... Idempotency: JSON Patch operations can be safely retried without causing unintended side effects. So, wait, you can't add an item to an array with this (except at a predefined position)? I.e. "add" with path "/.../myarray/~" (if I've understand their notation right) isn't allowed? I'm not sure if that's good or bad, but it's certainly surprising and could do with saying a bit more explicitly.
