This prevents extra IO. Different defaults are used for async backends
since we can’t assume that `existence_required` resulted in existence
synchronously.
StrategyWrapper was unnecessarily implemented as a LazyObject
and it triggered a bug in Django (issue 21840).
Changing the lazy object to a function works just as well and
bypasses the bug.
As discussed in #214, source_created and source_changed didn't really
have clear definitions. In truth, their names and separation betray
their origins as model receivers in earlier versions. The "source group"
abstraction helped us get away from thinking about things exclusively in
terms of models, but these remained as an artifact.
Differentiating between when the generated file content is required and
when the generated file is just required to exist gives us more
flexibility with strategies.
Changed my mind about 04aa72c1f9. It's
just a better description, even if different strategies can change the
behavior so it isn't really very cache-like.
