Since I am [in part] responsible for having the above checks in a  
consistent way, here's my part of the answer:

No. These limits exist because the header field in CompiledMethod has room  
for just these respective number of bits.

Has nothing to do with, how classes are represented in the VM, but with,  
how CompiledMethods are represented in the VM.

Correct. This way you have only one literal in the CompiledMethod, instead  
of one literals for each value less than -1 or greater than 2 :)
