Absence of `order` and `sort` in rest calls?

Question

Will absence of order and sort give the same result as order=desc and sort=activity always in every call (it is default in every call)?

Answer 1

Yes, much of the time, but:

1. Do not assume this is so, since it is never explicitly promised.
2. Some sortable routes do not even have an activity property (Example).

In this answer, the lead API developer says:

... ordering is descending by default.

This question and answer imply (but do not guarantee) that data is sorted by activity, by default (if activity is one of the returned object's properties).
