Description
occured to me during https://github.com/JuliaDiff/ChainRules.jl/pull/717
that there are like 3 states we really care about:
- Doesn't infer at all, so infers to
Anyor someUnionAllor abstract type - Infers down to a small union of <4 types, so the small union optimization kicks in
- Infers down to a single concrete type
The current check_inferred boolean doesn't allow us to distinguish case 1 from case 2.

Research direction
Start by reviewing the current check_inferred implementation and the context in ChainRules.jl pull request 717. Define how configuration distinguishes no inference, inference to a small union of fewer than four types, and inference to one concrete type; done means callers can reliably tell these three cases apart.
