For the activity itself, perhaps. It is detrimental, however, to the players on their home servers, choosing not to server hop, being locked out of participating due to the wanderers filling the area. Blocked from rewards that you should've had access to.

The event will be completed regardless, so there's no real benefit to have world visitors.
