Sometimes, a feature can get a thumbs-up for inclusion and then be cast aside. This happened with object.observe, for observation of changes to objects. It had been planned for inclusion this year but was withdrawn due to a change in the technical circumstances around it.
(I should explain for non-programmers what they mean by objects here. They mean “objects” in the computer sense. It’s not anything like a real-world object, such as the “buttery cream spread” that fast food places give you to smear on a potato or a biscuit. A computer programming “object” is an imaginary thingy that programs can make do stuff or have properties. Whereas “buttery cream spread” is just a promise that this is a thing with mass and color and a kind-of-definite shape, which you can place into your mouth and consume if you think that’s going to make you any happier. To computer programmers this would be an “interface”, which is a kind of object that is even more imaginary.)
And Krill just leaves that point there, as if it were enough. What change in “technical circumstances” could have removed the need for an object-change-observation feature? For that matter, what’s a “technical circumstance”? More to the point, what isn’t a “technical circumstance”? I suppose it wouldn’t be a “technical circumstance” if they were all set for the object-change-observation procedure announcement and then they couldn’t get on stage because an offended cow blocked the hallway. That would be more of a “natural correction”, of the problem that they couldn’t just go down the hallway? No, not if the cow was offended enough to chase after them. But I bet the cow would be offended about how the feature was supposed to be implemented, so there we go right back to a “technical circumstance”.
I bet the “technical circumstances” excuse was a cover. And that it all goes back to announcing the feature. I figure it was like when you decide you’re going to give your book report presentation by bringing in a cute puppet and having it describe the book from the perspective of a cow that witnessed most of the story. And then you run into the “technical problem” that the day of the presentation you get Doing Something Novel Stage Fright. That’s like normal stage fright, plus you’re scared everyone will laugh at you forever. And even though everybody would love you for doing the only non-boring presentation ever you chicken out.
