Is there any serious implementation of applications (e.g., FTP, HTTP,
...) using this interface? Or it is just a possibility, but nobody
ever implemented full-fledged applications based on it?

Is the establishment of the connection at the execution a command like this

`exec 3<>/dev/tcp/`

How to close this bidirectional connection?
