Other than getent, this file seems to be little use in a default EL7/EL8 system as route and netstat were 'deprecated' and have to be installed outside of default installs.
IIRC, the names in /etc/networks would be used in places like ip.wrappers and NFS exports. The earliest Solaris networks I worked with made pretty extensive use of that archaic kinda stuff.
