They do different things. The warnings against using os.system are
based on "If you don't know whether or not you have the use case that
this exists to handle it's much safer to assume that you don't", not
"This has no valid use cases" (your use case just has to meet the
criteria that makes os.system safe to use - no exposure to untrusted
input.

Cheers,
