The thing about these deprecated tools is that the replacements either suck, are too convoluted, don't give you the same info, or are overly verbose/obtuse.
ifconfig gave you the most relevant information for the network interfaces almost like a dashboard: IP, MAC address, link status, TX/RX packet counts and errors, etc. You can get that with ip but you've got to add a bunch of arguments, make multiple calls with different arguments, and it's still not quite what ifconfig was.
Similarly, iwconfig gave you that same "dashboard" like information for your wireless adapters. I use iw to configure but iwconfig was my go-to for viewing useful information about it. Don't get me started on how much I hate iw's syntax and verbosity.
They can pry scp out of my cold dead hands.
At least nftables is syntax-compatible.
