What does regimes mean here? Event horizons?
Context:
Conversely, in the 1970s, Hawking also showed that black holes can slowly shrink, spewing out 'Hawking radiation'. In that case, the event horizon would, in theory, become smaller than the apparent horizon. Hawking’s new suggestion is that the apparent horizon is the real boundary. “The absence of event horizons means that there are no black holes — in the sense of regimes from which light can't escape to infinity,” Hawking writes.

Does this definition help? Regime: the conditions under which a scientific or industrial process occurs. I think Hawking is suggesting that black holes, in the sense of a region of space with gravity so strong that not even light can escape, do not exist.
