Does anyone maintain an impl of the Chandler Carruth map API?

Lightning Talk (C++Now 2019, 8min): https://youtube.com/watch?v=kye4aD-KvTU

In 2019, Chandler presented the above talk describing a C++ map API. It's not compatible with the standard map types, but for greenfield projects I think it's an excellent choice.

I've considered implementing it myself, but hash tables are very subtle and finicky. I'd rather rely on a robust implementation.

Abseil has some excellent hash tables, but to my knowledge they do not support the small size/small buffer optimization. Chandler's hypothetical API does. Would be great to have the SIMD probing algorithm from Abseil implemented for an SSO map type.
