Also see United Airlines Flight 232 https://en.wikipedia.org/wiki/United_Airlines_Flight_232 which suffered a loss of all hydraulics and thus control surfaces. The crew and a check airmen who was aboard as a passenger managed to somewhat control the plane using engine thrust and managed to steer the plane to an airport before making a crash landing. They saved more than half the people on the plane.
One of the harrowing details is this quote: "The crew contacted United Airlines maintenance personnel via radio, but were told that the possibility of a total loss of hydraulics in a DC-10 was considered so remote that no procedure was established for such an event."
Amazing, I didn't know of this incident. Awesome airmanship.

Has this even changed? What can you even do in the extremely unlikely scenario of loss of all hydraulic systems? I don't think it's even possible to train for such a scenario. You are truly on your own. What would the checklist even look like? "try doing the best you can with engine thrust alone, and may god help your soul"?
As far as I'm aware, the engineering has gotten better (introduction of hydraulic fuses that keep a closed loop in case there's indications of leakage), but truly, what can you even be expected to do without flight controls.
