The potential benefit is developing novel viruses. That's it. They will likely be infectious. Hopefully, ahem, your operating protocols prevent the release of that virus and you study it in model organisms to figure out metabolic pathways to fight it before such a real virus occurs naturally.

I suppose I'm operating from the belief that everyone cares about preventing possible virologic doomsday weapons. I'm sure quite a few people have not the slightest concern.

So, we need to do more research until we will find an ultimate weapon against viruses.

As an alternative, we need to stop development of new viruses, both naturally and in labs, including Russian and North Korean labs.
