For many years at FB, suffixing dangerous or really-deprecated tokens with `_DO_NOT_USE_OR_YOU_WILL_BE_FIRED` was the standard. Everyone[^1] was in on the joke.
In the middle of the pandemic when ~50% of the workforce had started post-2020, it and other things became complaints for causing fear/uncertainty. We didn't do the best job on-boarding remote people and making them feel part of the culture at that time.
[^1]: It was a big company so this statement could only be true in the circles I had access to.
I remember seeing this in React's __SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED, and I've always enjoyed similar lighthearted and unwieldingly-long names.
Unfortunately I see it too has fallen victim to defunnification: https://github.com/facebook/react/pull/28789
