The key problems were:

1. spoilers are inherently opinion - there is no way to dictate neutrally what is and isn't a spoiler, and no referenceable source for such

2. spoilers were superfluous in many cases (a section labeled "Plot" or "Summary" is going to have details of the story in it)

3. a spoiler-warning culture was causing editorial problems: relevant information being removed from articles for being a spoiler, or articles being twisted into weird shapes to herd details into "spoiler" sections

4. the spoiler culture was getting gibberingly stupid (a spoiler warning on "Romeo and Juliet" and "The Three Little Pigs", I shit you not).

The thing I did was remove several thousand spoiler warnings from "Plot" or "Summary" sections, where they were superfluous. When those were gone, the other problems were enough for consensus to reach the death of the spoiler warning.

But let's assume spoiler warnings are a great idea. How would you implement 1. neutrally and verifiably in a manner that was hard to argue with?

1. In the example at hand, a possible solution would be to separate the mechanics of how the episodes aired from the content of the story itself. You don't need story details to have an explanation of how Season 5 of Breaking Bad was broken into two pieces that aired a year apart from each other.

2. The fact that a major character dies, is pretty arguably a spoiler. Obviously not for stories so common and/or old that they are tropes (e.g. Romeo and Juliet). Coming back to the example of Breaking Bad Season 5, knowing that a major character dies is probably universally accepted as a spoiler within the first year or so after it airs.

So how far do you go back? And for what countries and, indeed, cultures? Note that English Wikipedia is not American Wikipedia, but pretty much International Wikipedia. The world is a very big place. You still seem to be assuming I've asked you for "something obviously acceptable people like me", and that's not the case at all. What's a rule for people who are from somewhere that couldn't even tell you who Baba Yaga was, let alone a story about her?
