In [this comment](https://github.com/pypa/pep517/pull/48#discussion_r287282963), @gaborbernat suggests that the project should unconditionally fallback to setuptools if PEP 517 is not indicated. That seems like a plausible suggestion, but I'd like to separate that concern from the concern in the PR.
