Done.

I've also checked the usages of those functions:

* load_hashers() in django/contrib/auth/hashers.py
* get_storage() in django/contrib/formtools/wizard/storage/__init__.py
* default_storage() in  django/contrib/messages/storage/__init__.py
* Subclasses of SessionBase in  django/contrib/sessions/backends/
* get_finder() and get_finders() in django/contrib/staticfiles/finders.py
* Added AttributeError to _create_cache() in django/core/cache/__init__.py
* get_key_func() in django/core/cache/backends/base.py
* get_storage_class() in  django/core/files/storage.py
* load_handler() in django/core/files/uploadhandler.py
* load_middleware() (and its subclasses) in django/core/handlers/base.py: WSGIHandler in django/core/handlers/wsgi.py uses it, but wrap it with a `bare try: except:`.
* get_connection() in  django/core/mail/__init__.py
* get_cookie_signer() in django/core/signing.py
* ModelState.from_model in django/db/migrations/state.py
* CollectionRouter.routers in django/db/utils.py
* get_standard_processors in django/template/context.py
* find_template_loader() and find_template() in django/template/loader.py
* configure_logging() in django/utils/log.py
* get_exception_reporter_filter() in django/views/debug.py: AdminEmailHandler.emit() in django/utils/log.py uses it, but wrap it with `try: except Exception`.
