When is one available and when not? Why are we fine not delaying it
in some cases?

So the plan is to eventually have all callers pass it? If so that is
another argument to first always pass defer_ops through the transaction,
then make sure all callers have it where required, and only then move
to actually use it.

No need for either assert, we get nice clean NULL ptr dereferences when
this isn't true.
