Although it is true that this might reduce luring, it will greatly increase lag. To most players, the trad-off is not beneficial. If the wild recorded every death, every sword swipe, every time someone put a window in their house, we would need a supercomputer to run Meepcraft.
You state that this will help solve luring cases. All death logs will do is record that certain a player was killed by another certain player. This is just pvp, which is legal in wild. For the incident to be luring, screenshots are needed, which logs cannot provide.
This idea is unessicary and, if implemented, would be destructive to the play experience of Meepcraft.
