Well pkgbasify did it's stuff and I've rebooted. This is what is in the relevant files and if some clever #FreeBSD could confirm that they look OK then I'm officially using pkg from now on instead of freebsd-update.

# To disable a repository, instead of modifying or removing this file,
# create a /usr/local/etc/pkg/repos/FreeBSD.conf file, e.g.:
#
# mkdir -p /usr/local/etc/pkg/repos
# echo "FreeBSD-ports: { enabled: no }" > /usr/local/etc/pkg/repos/FreeBSD.conf
# echo "FreeBSD-ports-kmods: { enabled: no }" >> /usr/local/etc/pkg/repos/FreeBSD.conf
#
# Note that the FreeBSD-base repository is disabled by default.
