Maybe it's time to get rid of tcpwrappers/tcpd?

I have to say that there are certain out-of-the-box services that it’s nice to be able to block access at the application-level, which would be hard to do at the transport or network layer.

RPC-based services being the most obvious, but also things like FTP or TFTP or VNC or X that don’t always have port numbers that are easily expressed…  Then there’s filtering on DNS hostname suffixes, etc… NIS+ membership...

I’m fine with seeing systemd being decoupled from them, but I’d like to see legacy services continue to work with tcpwrappers (libwrap).
