There was a problem hiding this comment.
Somewhat concerned about how this affects the simulation story - is SimulatorBase now a valid superclass for external simulators? When should a simulator implement it vs. the other interfaces?
In related news, we really need to nail this down in documentation.

Fixes quantumlib#5400 Add a deprecation warning that _base_iterator is going to be made abstract, and copy (with intent to move) the implementation to SimulatorBase. Once the deprecation timeline has passed we can safely make `SimulatesIntermediateState._base_iterator` abstract, and remove `_create_simulation_state`, `_create_act_on_args` and `_core_iterator` declarations from `SimulatesIntermediateState` completely. This makes `SimulatesIntermediateState` more true to its name, as it should not be concerned with how or where the subclass creates the initial state, even from the interface standpoint. @95-martin-orion
