I did IT support at a car dealership where some ancient line-of-business software needed a public IP for every Windows desktop it ran on to function properly.

No justifiable purpose, sure, but I can only imagine the tons and tons of legacy line-of-business crap out there with assumptions like this.

You nailed why I threw in the word justified intentionally. There’s plenty of reasons a public IP could be needed, but not justifiably (to me, your example perfectly illustrates that).
