Gravestones (You shouldn't have a deleting timer on your hard earned gear)

In minecraft normally after you die, your items are thrown out on the ground and despawns after about 5 minutes after being in loaded chunks.
But sometimes said items could be in a difficult to reach location and might need time to prepair (such as if someone died in a trial chamber with spawners, they would need to fight through the mobs with what gear?)
So I suggest adding a mechanic similar to some gravestone mods that create a grave on player death, this grave will store players' items where they died so they still have to get to where they lost their stuff but their items wont be deleted forever.
I really hope people consider this idea
thanks a bunch :]
