My 2 cents worth, which basically agrees with some of the other replies here.
Tankslappers are generally a result of some inherent handling issue with the bike. ie frame geometry, tyre wear, suspension setup etc. This is why tankslappers were far more common on much older designed bikes. eg those big bore bikes in the 80's which started to produce more power than their frame designs, geometry and suspension were capable of managing. Hence some people referring to 34 years ago.
Engineering & design on today's bikes have improved handling significantly. In my opinion, it would be extremely rare to experience a tankslapper on something with the wheelbase (long wheelbase equates to stability), weight & fitted steering dampner of a Busa, unless there is something else wrong. eg tyre wear, suspension setup.
Powering out works because it unloads the front wheel as the acceleration forces transfer weight onto the back wheel. By throttling off, weight is further transferred onto the front wheel, which is the cause of the tankslapper in the first place & will only make a bad situation worse.
There may be situations where road conditions matched with certain mechanical conditions (ie speed, acceleration, decceleration, weight distribution etc) can cause a modern bike to experience a tankslapper, but these would be rare. If it occurred, I would be looking at some of the inherent issues I mentioned initially.
Some modern bikes eg. certain models ZX10 are more prone due to the power, wheelbase, rake/trail, swingarm length but the Busa wouldn't obviously be in this category.
