Re: not only DNS
This considering that NTP monlist is a old and it's already patched.

NTP can be easly blocked inside the network.

UDP may not be blocked in efficient ways if is needed.

Is there a larger concern?
Reading between the lines of this article there appears to be a larger concern which is not directly called out.  Because we continue to focus on the traditional threat-based control approaches, such as encryption to protect against eavesdropping or certificates for authentication, are we inadvertently creating "blind" spots that increase opportunities for these attacks?

This is not to say that all existing security countermeasures are failing us but that perhaps we might have a better chance of surviving this modern threat landscape by re-evaluating the use of traditional threat-based approaches and focus on reducing our attack surfaces by following a more risk-based approach.

Re: not only DNS
The uptick in NTP and SNMP-based DDoS attacks is interesting. These are also protocols that are forgotten or overlooked by the security team.

not only DNS
The number of DDoS attacks is increasing causing even more serious problems.

Not only DNS amplification attacks are threatening the security communities, recently cyber criminals abused also of NTP and SNMP protocols.

Looking the Bandwidth amplification factor we can note that a DNS DDOS has a factor ranging from 28 to 54, meanwhile NTP has a traffic amplification factor of 550.
