I understand, the diadem is no longer versatile because it has been permanently fixed.
For the Investiture of the new King, the diadem has been reset again. It has a new and different frame which apparently helps the stability. The central prong was removed, so maybe the original design has been respected again and the diadem was made semi-detachable again.
