Actually a possible 'reason' for this just occurred to me.
If you're buying a DNS hosting service from an ISP, does the ISP have the right
to cancel said hosting service without authority from the customer?
This, I believe, has been a cited reason _not_ to remove legacy DNS (despite
what the registry says) for at least one provider i've heard of before now. It
makes the issue one of customer-provider liason - and one of
monetary/commercial significance - instead of dns/operational significance.
I favour the latter. But there may be a valid point here...
