This allows to redefine an existing non-inheritable constraint to be inheritable, which allows to straighten up situations with NO INHERIT constraints so that thay can become normal constraints without having to re-verify existing data. For existing inheritance children this may require creating additional constraints, if they don't exist already. It also allows to do the opposite, if only for symmetry.
