I just realized that for some of these we are only specifying an enum value (SN_whatever), and for some of them we are specifying op codes. Why the difference?

It depends if it is necessary to have the opcode or not. For SN_get_IsSupported, all we needed to to was
if (id == SN_get_IsSupported) {
EMIT_NEW_ICONST (cfg, ins, supported ? 1 : 0);
return ins;
}
For the methods with op codes that I have been working on, they went through this common logic:
