I've coded a ton of shell scripts over the years and never actually considered this nor has anyone I know ever intentionally[1] put protections for it in their scripts so I think the original comment may be overestimating when they say "most of us"

With that said, I definitely ill be looking out for this in the future.

[1] I have unintentionally protected against this by using unique names for my temp files.
