If I have a grid in batch edit mode with numeric columns that add the numeric Editor to the cell, I need it so that when the field value is 0 (zero) it either shows as blank or highlights the zero so a user can type the value without the superfluous zero. In other words, a data-entry person using the keyboard (over the spinner) to navigate the grid and enter data, will need to do extra work to prevent the value from staying as "4000" when they intend to enter "400", b/c the cursor by is to the left of the default value. I've done this myself many times in unit testing. It's an annoying trait when they want to do rapid keyboard-based data entry.
