Thanks for finding the bug, I think I would rather transform the fallback into a hard TODO like below because as you mentioned the change is a workaround that is not always valid, so I want to make sure this is never allowed to compile end-to-end when going through that path.

```
if (!componentParentType)
  TODO(loc, "parameterized derived types");
```
