> no card of MtG is allowed to mention the stack in their printed text

Nit: The Split Second keyword ability is usually accompanied by reminder text which mentions the stack

> Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.)

Welp, that's true, my bad! It seems this rule was relaxed somewhat - mentioning the stack in the rules text is still frowned upon, but there's still some cards that mention it in the rules text (and a lot more that contains the split second reminder)

Note how the waterhouse's link - https://gatherer.wizards.com/Pages/Search/Default.aspx?actio... - contains a bunch of cards that were playtested but eventually rejected (they are the black-and-white cards with just a rough sketch in place of art), presumably because of the high bar that stack-fiddling cards should meet

Doing a search, I count 40 results with "stack" in their text; it appears that 18 of them have "split second", a few of them have "stack" in their name, several are from "Un" expansions or this weird "Mystery Booster" thing, several mention the stack in explanatory text about what it means to end the turn or end the combat phase... but there are several cards such as Grip of Chaos ("Whenever a spell or ability is put onto the stack, if it has a single target, reselect its target at random") that are from regular expansions.

Is this a recent standards change? I remember some legendary artifact that caused spells on the stack to be copied and explicitly described it that way.
