 I think it's simply not a part of the architecture.  IOW they are free to 
remove it at any time, though most likely it will be kept forever.  It's 
not like rocket science or whatever else to be kept hidden -- "everybody" 
knows this instruction (myself for at least 15 years).  That's stuff like 
FFREEP, etc. ;)
