You have to opt in with the lazy import keyword no matter what. This pep also prevents lazy import in try catch. I think your concern matters if ‘module’ itself has a lazy import that you want to check exists. With this you now need to be more rigorous in check those sub dependencies.

This can already happen with non top level imports so it is not a necessarily a new issue, but could become more prevalent if there is an overall uptake in this feature for optional dependencies.
