In PR #4983 we had to disable some code that made GAP use IsZmodnZVectorRep/IsZmodnZMatrixRep (added by @hulpke to speed up various computations) in certain situations because this caused regressions that blocked GAP 4.12.
We should now look into ways to make it possible to reap the benefit from IsZmodnZVectorRep/IsZmodnZMatrixRep without that breakage.
