One of application of Calabi-ansatz is choosing inital metric to run the Kahler Ricci flow, So if you want to using minimal model program and apply Kahler Ricci flow to find canonical metric study of such Calabi-ansatz would be very important. In fact study of Calabi-ansatz give an effective way to find inital metric and its connection with semi-flat metric. The question is still open

One application of Calabi-Ansatz is choosing inital metric to run the Kahler–Ricci flow. So if you want to use minimal model program and apply Kahler–Ricci flow to find canonical metric study of such Calabi-Ansatz would be very important. In fact study of Calabi-Ansatz gives an effective way to find inital metric and its connection with semi-flat metric. The question is still open.
