Am I missing something other than "nice to have"?

Yessir,..I think so.
The REAL value of an LSD is stability. Its much more than just wheelspin control which some people can manage.
Have you noticed how the rear end of your car moves from side-to-side under hard braking during corner entry? The harder you stop, the more the rear end moves around and its quite disconcerting, especially from high speeds. This is due to the rear wheels rotating at different speeds, relative to each other. Open differentials and torque-sensing diffs (which open under trailing throttle) display the same characteristics.
Cars with LSD's keep the rear wheels locked together under trailing throttle at the same speed and this
really stabilizes the car at a very critical time. Given a 911's the polar moment of inertial, one cannot always brake to capacity for this reason as such phenomenon makes for some sphincter-tightening moments.
The difference is truly quite dramatic.
Today's LSD's featuring asymmetrical (and adjustable) ramps make huge improvements in handling and allow a driver to fine tune corner entry & exit behavior, as well.
You would be pleasantly surprised how this would improve your car.
