Documentation for AttributeImpl.callable_ still reads
"optional function which generates a callable based on a parent
instance, which produces the "default" values for a scalar or
collection attribute when it's first accessed, if not present
already."
But it seems it is no longer the function which generates a callable,
but rather /is /the callable itself now, accepting both the state and
the passive parameters.
It used to be two stages, first callable_ accepts a state and then that
returns a callable which accepted the passive parameter.
Can you briefly summarize how this is meant to work now? (I think the
doc string is wrong now??)

yes a few change names, reconstruct_instance, init_instance, init_failed.

Right. And reconstruct_instance() was renamed load()?

As the migration guide suggests, I'd like to embrace the events API.
Is mapper event load() invoked at exactly the same place as the
deprecated reconstruct_instance() ?
yeah nothing has been moved. All the places where the internals would call
XXXExtension.xxx_event() were just replaced with self.dispatch.xxx_event(), and
the old Extension classes are invoked via an adapter to the new system. All
unit tests for the extension system remain in place and haven't been modified.
