Being a negative check, I'd live it as it is. Otherwise, if you introduce a bug that generates something slightly different, say `{ "aaa", 0x0, 0x0, 0x1 },`, you won't be able to prevent the regression. Essentially the `CHECK-NOT` is checking `isNeeded=0`, not the specific values passed to the `AEntry` class.
