NAT devices not translating privileged ports

Folks,
While discussing port randomization (in the context of
https://www.ietf.org/archive/id/draft-ietf-ntp-port-randomization-06.txt
), it has been raised to us that some NAT devices do not translate the
source port if the source port is a privileged port (<1024).
Any clues/examples of this type of NATs?
Thanks!
Regards,
