Please put an end to this. This exists for literally no reason other than to allow players an easy way to grief one another, whether intentionally or not, and it's not like gatherers have a free choice of where to gather like crafters do with their crafting.
Tbh, an argument could potentially be made for not allowing AoEs to hit any players who do not have any sort of aggro on the enemy using the AoE, but at the very least this should be applied to DoLs in gathering mode, who have no ability to move and can even lose out on unspoiled nodes or mooched fish this way.
