Description
Sometimes you actually do want the jacobian of a function. If this function is a vector->vector function, the Jacobian is a matrix. It's not immediately obvious how to define the jacobian for, say, a function that accepts a struct and returns a struct. It would be nice to figure out some sensible conventions here.

Research direction
This issue is a design proposal for Jacobians of functions with structured inputs and outputs, such as struct-to-struct functions. Start by reviewing the existing Jacobian conventions in ChainRulesCore and related automatic-differentiation rules. Done means reaching and documenting a sensible convention for these cases.
