I think that'll get way more common with time, eg no one would acknowledge September 11th at first but now I think if you watched a tv show set in the year 2020-2024 they'd acknowledge that as part of the history. There's 2 reasons I can think why you wouldn't want to include a recent event, the biggest one obviously is that TV is escapism and people don't want to see their troubles highlighted in their escapism story (and also advertisers might not want their products displayed on anything mentioning traumatic recent events), but another is that when you're writing for a tv show in the modern worlds, you don't really expect to do as much creative worldbuilding as you would for a fantasy show. But if you include recent events that are going to cause a huge geopolitical ripple, you won't be able to predict as well what happens next.
