With JSF 2.2 client window API, it has sense to change the default value for
org.apache.myfaces.NUMBER_OF_SEQUENTIAL_VIEWS_IN_SESSION from null to 4.
Since we have already the default of org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION to 20, with this we will have by default 20 / 4 = 5 slots to hold client windows.
