See PR 56736, there since Sep 2003:
  <http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/56736>

If you don't like it, please provide feedback what you think can be improved.

Except the /usr/local/etc/rc.conf this is what a lot of ports already do.

I guess we don't need this (and shouldn't do it, since ${PREFIX}/etc/defaults/rc.conf
might be read-only). Defaulting xxx_enable to "NO" seems to be sufficient, with

  [ -z "$xxx_enable" ] && xxx_enable="NO"
or
  xxx_enable=${xxx_enable:-"NO"}
before calling load_rc_config $name

Adding /usr/local/etc/rc.conf maybe a good idea, but I don't see the need
for a /usr/local/etc/defaults/rc.conf.

See above. If I get feedback I well incorporate /usr/local/etc/defaults/rc.conf
support in PR 56736.
