In fact, update-rc.d only ever calls insserv if
/etc/init.d/.legacy-bootordering does not exist, which it should for all
Ubuntu systems:

if ( ! -f "/etc/init.d/.legacy-bootordering" ) {
    info("using dependency based boot sequencing");
    exit insserv_updatercd(@ARGV);
}

Having update-rc.d fail for users who have manually removed this file is
probably the lesser evil, and fixable by having them re-create the flag
file.
