I thought this is not oficially recommended for ordinary users to prevent
root servers from being overloaded (transfers use much more resources
than
ordinary lookups). Has this changed?

ICANN run a specifc AXFR service for various infrastructure zones:

http://dns.icann.org/services/axfr/

...which IIRC some configs for root-slaving (FreeBSD?) use by default.

It's not used by default, but it is in the config, commented out.
