Memory-Alpha is saying that the show takes place in 2397, because of the '10 year anniversary' line about the supernova.
2397 makes sense, because we know that Picard was born in 2305, and he's canonically 92 here.
Careful, let's not conflate things! Laris (the Romulan woman at Chateau Picard) says that she's been reminding Picard of such-and-such for ten years, implying she's been with the household that long but
not that the supernova was exactly that long ago. The interviewer later introduces Picard by saying that today is the anniversary of the supernova, but
not specifically the tenth anniversary. And the show never states that Picard is 92; AFAIK that was only an off-the-cuff remark from Michael Chabon.
What we do know specifically from the episode is that Data painted the painting Picard notices "in 2369," which was "thirty years ago," and later that Data's death (in
Nemesis, conventionally dated to 2379) was "over two decades ago." Assuming that "over" is ambiguous enough to be read as "not less than," the most logical date for the opening episode of
Picard is sometime in 2399.
Doesn't mean it's nothing. If it's a good story, it didn't stop being a good story just because it isn't "canon" anymore.
Did you enjoy reading it back in the day? Have you lost that experience? ...
A good comic book is never "nothing" as long as people enjoyed reading it, regardless if we're talking about STAR TREK or an old Silver Age BATMAN comic.
As a general rule, I'm inclined to agree with you. I think there's room for a category of exceptions, though, and that something like
ST:Countdown falls into it. It's really not a story designed to be enjoyed on its own. Whatever makes it enjoyable is precisely its
connection to the larger mythos, to events and characters with whom we already have a connection, and, hence, about which we want to fill in the gaps. (FWIW, I read
Countdown at the time, and I currently remember next to nothing about it except for a few points of continuity.) Strip away that connection by saying that its continuity is no longer valid, and it has very little enjoyment left to offer... and meanwhile whatever questions it answered are retroactively re-opened.
