Why is it hard to add server-side detection for line-of-sight when a player shoots at another player? The client should not be telling the server "I shot Player 2 and did X damage". Instead, the client should be saying "I shot in X direction at Y time" and the server should be reconstructing the world at Y time (As described in the Lag Compensation page of the article) to determine a hit. The server should be performing line-of-sight checks.
In a game like PUBG, there's no reason a player should be popping headshots against players a mile away when there's a hill and/or several buildings between them. But the game allows clients to decide when they score a hit. At least, it did in the past.
