That's on you. A lot of code use list instead of set purely because set is rarely a basic primitive language offers.

If I see method returning list of users I'm just gonna assume it is unordered, and it usually is unordered.

If you return list that's ordered and that matters for some reason, the docs should say it is ordered and by which key.

If the method is called RunTasks(list) and documentation is "runs a list of tasks" it is perfectly fine to assume it means "runs list of tasks in order" but it is also perfectly fine to assume "runs all of the tasks in parallel".
