	Vendors have never wanted to publish this, nor have they been
willing to truly document it.

	It seems like this is just an excuse to let their whim of the day
be further propogated.

	As someone who actually reads the diffs from the nvgen
ecosystem in platforms like Cisco IOS, it's clear nobody really
reads the full system diffs.
	
	Claiming otherwise is clouding the discussion.  Once again, this is
"We will never ever secure our BGP implementation".  To that, I will
respond accordingly with my account team.

	I also question those who think customers can't easily figure out
how to turn a knob on.  You must really not think highly of your customers.

	- Jared
