Has this been resolved in wrapt itself? Can we resolve it by vendoring a new version, or even adding wrapt as a dependency?

Nope: https://github.com/GrahamDumpleton/wrapt/blob/develop/src/wrapt/importer.py#L94. We could make the upstream contribution, release a new version then vendor it but that seems like a pain.

[majorgreys]

@mabdinur I see your point. We can make this change here and also contribute upstream.

We'll want to run all tests given this change.

[mabdinur]

We may need to bump pybind11: pybind/pybind11#4941
