Putting a DatePicker in a datagrid

This is such a common requirement I'm surprised Microsoft hasn't added a DataGridDatePickerColumn but they haven't so every time we want a DatePicker in a DataGrid we have to go through the convolutions below...

<DataGrid ItemsSource="{Binding Path=Events}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Event Date" Width="200">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=EventDate,StringFormat=MM/dd/yyyy}"></TextBlock>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <DatePicker SelectedDate="{Binding Path=EventDate}"></DatePicker>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>
