I has a load of fun when I discovered this too, but eventually realised that a good cli app has focus, sensible use of opts, a succinct -h, reliable exit codes and above all easily parsed output on stdout.
I am all about sensible options, reliable exit codes, and easily parsed output on stdout--but easily parsed output on stdout when it isn't a tty is different from what you show a person when it is a tty.
It's also fairly straightforward to strip escape codes if you need to using sed or similar[0], and there probably already exists a tool that will do just that specifically and more robustly than my example.
