What observable properties of black holes may be explained by the

Black hole evaporation. I am thinking about some work by Hawking.
But $any* true erasing of information is forbid in any theory where QM
applies universally. Unitary evolution cannot erase information,
although it can hide it and makes it very hard to recompose.
Is that a purely hypothetical suggestion, or is it something we may
observe in the near future, or may have already observed, indirectly?
I think some cosmological observations confirm this. It makes QM
necessary to justify the existence and stability of Black Hole.
