If you depreciate and then remove os.system, all you will do is force
people to re-invent it, badly and inefficiently.

Indeed. Usability counts, as does not arbitrarily breaking vast amounts of existing code that Just Works.

Every code-breaking deprecation is an invitation for unseen thousands or millions to ponder, "Hm, this script doesn't work anymore. Maybe now is the time to look at Node or Rust."
