While I like systemd and its related projects, I have not yet switched
to systemd-timesyncd.
And I was not implying Debian installs ntp by default, merely that the
package comes with IMO insecure defaults.

See, that's why I asked for a second opinion.
I explicitly installed the ntp package, and mine came with this as
default:
# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited
I commented these out, and left the next stanza, which *is* a
restriction to localhost.
