Review Comment:
i think it's unnecessary to change the signature of this function and add
the other two wrapper functions.
just build the exception object and pass it
```
e = TaskDeferred(trigger=BaseTrigger(...), method_name="...", ...)
```
unfortunately, we don't have integration tests set up for AIP-44 but if we
did then it would reveal that this will break that mode of execution because
for example there's no mechanism for serializing `Trigger`, possibly among
other things.
obviously it's not your fault and a shortcoming of the current state, but in
any case i think it will be simpler anyway to keep the existing signature and
just build and exc object that you don't raise.
