What is this for?

add_fallbacks! is used to populate the operating point with values from defaults if not explicitly provided, handling array variables and reporting the variables that don't have a default or an entry in u0map/pmap. The bug was get(fallbacks, var, nothing)[idx]) for scalarized array variables, where if var isn't present in fallbacks it would try to call getindex(::Nothing, ::CartesianIndex) which doesn't work. I just managed to MWE it and added a test.
