It is not a scaling issue.  You are touching the servers anyway to
configure them to serve the zone.  How much work is it to *automatically*
add the addresses of the losing providers nameservers to the allow
transfer acl for the zone?  A couple of milliseconds.

This is all lack of willingness on behalf of the DNS providers and
nothing else.  They all got in to the business knowing that this
was how it should be done.
