Modern ejection systems are zero-zero systems designed to allow ejection at zero speed and zero altitude which means that the aircraft may not have enough energy to successfuly destroy sensitive components across the full ejection envelope.

Why not rig it with explosives around the sensitive components and avoid the messy endeavor of trying to orient the plane for maximum destruction after ejection when that is likely to be unreliable at best?

Because then you would have introduce a brand new safety-critical system that also happens to be the most dangerous on the aircraft.
