Well, if you do not initialize slots with NIL, how can people know when
it's safe to call an accessor?
Checking SLOT-BOUNDP would mean that users have to know about internal
implementation issues: the slot names.
In ASDF, it's especially icky because slots tend to have different names
than accessors, so you really have to look into the source.
