They are useful for troubleshooting and diagnostic purposes.   Just be
sure to limit the maximum possible response rate and bandwidth for any
source network,   and be sure to truncate the length of the response
to the length of the original query,  so they cannot be used for
amplification.   If you can't do that, then shut them off :)

The risk that they be used to DoS the server that runs those services remains.
