I gotta ask this. If v5.12 arrived with !0 returning 4, and the OP code broke, would the fix be to the OP code, or to v5.12?
Also, "dangerous" is usually reserved for things that threaten life or limb. Under any circumstance where code could possibly be dangerous in that sense, any such fundemental change to the implementation, documented or not, would surely be detected during the obligatory, extensive system and regression testing that any software in such a life critical application would have to undergo?

In the absence of evidence, opinion is indistinguishable from prejudice.
