They don't really explain the significance. They mention names of people are known and you could make theories as to how that MIGHT be useful ... but it's not clear if it actually is actionable type information.
It most certainly isn't actionable because they aren't making any bombers anymore. Ukraine isn't trying to shoot down any of them (they are not using within, or close to, Ukrainian airspace), so whatever knowledge they might gain isn't too actionable. Maybe only as something to sell to the West.
