Wicket: can I safely ignore serializable warnings?

Almost all of the Wicket components need a line like this

private static final long serialVersionUID = 1L;

And sometimes there are too many those distracting lines... In which cases we can safely ignore serializable warnings? For example:

@SuppressWarnings("serial")
public class CheckOut extends WebPage {
    //private static final long serialVersionUID = 1L;
    public CheckOut() {
        ...

    @Override
    protected void populateItem(ListItem<Cheese> item) {
        //private static final long serialVersionUID = 1L;
        ...

These are needed only if you want to support persistent sessions [1]. You can ignore them otherwise.
