IDK, environment variables get set all of the time, I rarely worry about them breaking programs. Their job is kinda to live in the background and be passed through programs so it doesn't feel like much danger. Especially when I use lowercase and almost all programs use uppercase. But I guess everyone has a different risk level and what feels near-zero to me is meaningful to someone else.
