And, given that massive lack of specificity, should anyone care?

I mean, yes, in a general sense, it's notable, but it doesn't tell me how often it has happened or who the target is, so there's no personal value nor any substantial value from a civil liberties perspective because it doesn't tell us all that much.

They never will be able to tell down to the person level. Those would definitely violate the gag order, which if you're willing to violate why go through the mess of a canary. Similarly the government is very particular about reporting just how often they're received. Testing that is a huge gamble on the lawsuit that would be filed when you get too precise for the government's tastes.
