It would lead to significantly less arrests if they needed double or triple the agents to conduct them “safely”.
More people will die only if agents or their victims start shooting on general principle. In either case, that’s a backslide that isn’t really a consequence of putting more agents on one person.
Given that this would lead to slightly less arrests but significantly more deaths, I’m not sure how this would be considered a win.
What do you think is going to happen when dozens of agents start raiding homes without a warrant?
