I was thinking more about proxying the class itself, something like
```python
class _XComMeta(type):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self._impl = resolve_xcom_backend()
def __getattr__(self, name):
return getattr(self._impl, name)
class XCom(BaseXCom, metaclass=_XComMeta):
def __new__(cls, *args, **kwargs):
return cls._impl(*args, **kwargs)
```
There are other things that need consideration such as `__issubclass__` and
`__isinstance__`, but it should be possible with the right tweaks to the code
base. Whether that’s too much work, however…
