It's the same change that was applied to Crucible loading times as a QoL fix.

In Crucible it just means sitting in the flight screen instead of a black screen while loading everyone in. Unfortunately in the tower it means you cant load in on your own if someone else starts joining the same instance while you're en route. Have to wait for everyone, and with no matchmaking you can get a very slow trickle.

Reddit info though so pinch of salt.
