I imagine because vsync and triple buffering introduce latency. There are cases like games where you don't want all that lag.

If the goal was to reduce latency, wouldn’t you want the desktop compositor out of the way when vsync is on?

That's very true, and I believe Wayland has a DRM leasing extension just for this use case. SteamVR uses it to punch through the compositor and draw straight to the screen.
