	Actually it doesn't.  If you configure a trust-anchor for
	your own company you don't want anything overriding it.
	Having that overridden would be POLA violation.

	Having things break because you stopped managing/tracking
	them is not a POLA violation.

	For . and ORG I agree.  For ORG and ISC.ORG I disagree.
	For wattle.id.au (when it is signed) and andrews.wattlet.id.au
	I disagree.  There are couple of hundred zones where your
	policy makes sense.  There are millions where named's default
	policy will make sense.

	Your policy model make sense if you *start* doing DNSSEC
	during the bottom up development phase.  If you start in
	the top down phase it doesn't and top down is the long term
