I'll provide a general response, and then maybe see if any colleagues have a specific example to point to.
It's important that, in this subclause, the use of the word “may” connotes an illustrative list, so here's a list of things that the situation may require, and one of these things would be done, whereas the use of the word “must” suggests this is a definitive list, so they would be using this list and not their awareness of the situation and other options that may be out there. My understanding is that this list is intended to be illustrative, not definitive or exhaustive. That's the overarching point.
I don't know if any of my colleagues have an example to point to.
