1. This does not concern restrictions to sufficiently small deviations from thermal equilibrium, such as described in terms of (non-)linear response theory, which only involve thermal equilibrium correlators in real time.
2. Note that restrictions to mean-field type approximations such as leading-order large-N are insufficient. They suffer from the presence of an infinite number of spurious conserved quantities, and are known to fail to describe thermalization. Secularity enters the required next-to-leading order corrections and beyond. (Cf. Sec. 4.)
