I agree with that. Modern Unix is a 6-of-one-half-dozen-of-another type situation. Yes, terminal emulators and the termcap database are improved. But now, the traditional Unix user might be surprised at how things are done. I have accepted that ... systemd ... manages my networking now (ok, it's networkd or something I guess?). But if you can't accept that, it's good to have some option that just uses ifconfig.
