You can still strictly adhere to section III if you choose to - by only loading the environment variables, but Externalized Properties allows more than that if needed.
By using ExternalizedProperties instead of direct System.getenv() you get other useful features such as automatic conversions, variable expansion, and processing (e.g. automatic decryption/automatic base64 decode, etc)
