This feature is mostly focused on the other end of the communication, on being able to create new Terminal windows to run shells inside of them.
cmd.exe is a shell, and that's the guy that's parked.
conhost.exe is a terminal, and that's under active development, though it's slower than something like VsCode, because we can't just go adding features as we see fit, we have a LOT of back compat we still need to support.
Fortunately, conpty will allow for the creation of new terminal applications on Windows. If you're looking for a better shell experience on windows, I can point you to powershell or even [yori](http://www.malsmith.net/yori/), which looks pretty cool
cmd.exe is a shell
conhost and cmder are terminals.
I believe cmder can come with git bash as well, which is also a shell.
The confusion comes from when you launch cmd, the window that appears by default is conhost, with cmd running attached to it. When you launch cmder, it's also running attached to cmd.
