>Maybe I live under a rock, but I feel like command line utilities taking environment variable arguments just isn’t that common of a practice?
Nope, it's quite common. Many standard UNIX cli utilities take some environment variables (including things like LOCALE). Also common in scripts, setting up programming languages paths, etc.
It's also not a bad practice, contrary to what the author says.
