<https://github.com/pantsbuild/pants/issues/19158|#19158 `__defaults__` silently allows-and-ignores fallthrough kwargs>
Issue created by <https://github.com/thejcannon|thejcannon>
*Describe the bug*  
I was trying to do:

```
__defaults__(python_test=dict(environment="focal-docker"))
```

and getting frustrated it wasn't working.

Turns out it just gets collected and ignored:
