Description

The most recent iteration of this discussion was https://github.com/FluxML/NNlib.jl/pull/434, but it goes back to https://github.com/JuliaDiff/ChainRulesCore.jl/issues/547 and much further. Given that not all ADs are ChainRules compatible but this package seeks to support (/eventually be supported by) all ADs, it feels like a much better home for such functionality than a domain-specific package like NNlib.

Research direction

The work is complete when the project has an agreed API for user code to detect differentiation across the automatic-differentiation systems it aims to support.
