At least ftp and telnet still have their occasional uses, and being without encryption, have been removed on reasonably new macOS versions. So inetutils is useful. But the compulsory "g" prefix is annoying, whereas putting /opt/local/libexec/gnubin at the end of one's PATH so that at least SOME version of telnet, ftp, etc is found, is a simple way to keep scripts working, etc*.
* ok, some that depend on particular options or .netrc features or subcommands (run under "expect" for instance) might not be altogether compatibly scriptable compared to the removed versions, but they're a heckuva lot better than nothing; and it's enough of a reminder to re-evaluate the need for them that one would have to modify one's PATH, to be a bit silly to have one also modify scripts in the case where the only difference was the "g" prefix.
