Well, it's not that cumbersome... If you look at CPU encodings, they also tend to have different opcodes for different immediate lengths. In your case, I'd say it mostly leads to a bit of code duplication. But the opcode space is far from exhausted right now :)
Oops... Make that "in our case", of course.
cheers
Antoine.
