I guess the goal is to ease turning on asserts in all classes except for system classes (behaviour of -ea switch in its no-argument form.)As a consequence, a special switch has been added to turn on assertion for all system classes.

Because you will usually only want them turned on for your own classes, not for the standard API which is debugged already.
