Review Comment:
Agree with @ashb additional wrapper is no-go - it adds a lot of boilerplate
code and readability suffers. What I would suggest you to do is to explore the
capabilities that `attrs` custom init or pre_init does.
* https://www.attrs.org/en/stable/init.html#pre-init
* https://www.attrs.org/en/stable/init.html#custom-init
You could likely modify `DAG` to use custom init and wrap the
`__attrs_init__` with `try/except` and handle constructor failures this way.
