> Does it make a difference having a real inspector vs just always using an 'empty' signature? I think some things can decide not to vectorize if input types aren't known. One example is `FallbackVectorProcessor` which requires a known `outputType`, and the output type might be unknown (i.e. `null`) if the input type is unknown. I'm not sure if this is "correct" -- maybe it should allow vectorization of unknown types? -- but it is a thing currently. -- This is an automated message from the Apache Git Service.
