The IANA has a .csv file containing a list of all assigned port numbers.
Can we use this file to automate future updates to /etc/services?

That file has maybe 11k services in itabout 50 added in 2016 so far. The current Gentoo /etc/services has about 1118 services in it. Maybe worth a shot to just pull in the 10k entries Gentoo is missing?
