Thanks, Johannes.
In my case, shock decomposition is yet another output, and I am still using other oo_ substructures, whose content suddenly changes. Besides removing the distributional information in oo_.SmoothedVariables, also the ordering of variables in oo_.FilteredVariablesKStepAhead is changed, so that I have to modify the code for e.g. plotting the forecasting behavior, depending on whether shock_decomposition is switched on or off. This is a minor issue though, so the standardization of output depends mainly on the developers’ preferences.
