1. Since swap module is disabled by default, swap detection is unnecessary in most cases. 2. On platform other than Linux, swap detection doesn't share code with memory. 3. Swap detection can be expensive. On Windows, it requires another WMI query which can lag heavily in some cases. Don't pay for you don't use.
