something to consider with querying the terminal for capabilities / terminal size etc, is where there is no terminal actually connected at the time. this would cause it to hang or require timeouts or other complications. but i guess querying might only occur after user input. Again, as long as its all optional, people can apply what they like.
this is something i really love about NuttX. nice and lean baseline but so much discoverable behind kconfig options. again, i'll put together a basic proposal for ANSI support in NSH and see what people think of the implementation.
