Yup, magnetic brakes were originally introduced for the beginning angler BUT as with most things in life put it into the hands of an expert and it begins to do wonderful things. Consider the centrifugal brake as axe and the magnetic brake as a stiletto.
The centrifugal brake is perfect for throwing heavy baits, like cranks, spinnerbaits and T and C rigged plastics long distances or flippin' heavy jigs and worms at rod tip range.
Magnetic brakes provide precision spool control for tactics such as skipping a bait, pitchin' a bait and finesse plastics. it takes just as much thumb control to skip a bait using casting tackle, if not more so.
It's boils down to the old shop class adage, "Use the right tool for the right job."
