>not an unrelated system that just happens to be governed by an identical set of equations in some regime.

that is exactly the point of analogue systems - identical equations have identical solutions, and thus analogue system allows to observe and explore the solutions (which in many cases aren't that easy/possible to obtain mathematically/numerically)

We have no experimental evidence that the calculations for gravitational Hawking radiation (or their physical interpretation) are valid. The notion that dumb holes exhibit all the same properties as black holes is conjectural.
