Ask yourself this question.
I would like to be able to set up a vehicle that I can choose wheather to use v4 motor or v8 motor. That's so when I toss a car key to this kid, he will only use the vehicle with V4 motor enabled. When I take this same car key, I want to use a vehicle with a V8. Can both V4 and V8 co-exist in a single vehicle?
Kernel is similar to a motor in a PC. What's bad is that you also re-compile every binary (make buildworld and make makekernel) to be supported with amd64 optimizations to make it a amd64 system. You would have to do the same if you want it to be an i386 system.
You can't flip back and forth between a different architecture to another architecture based on only the kernel swapping as you can do with a car if you swap the motors back and forth (with huge amount of physical work).
