If someone changes an opcode in the VM to bring old behaviour back

I'm not sure what you mean but if external behaviour is the same then
it's not a fork. If syntax or semantics change, it's a fork.

OP_SELF changed between 5.3.(?) and 5.3.4. Originally it accepted any object as key, but since at least 5.3.4 it only accepts strings. Would changing this back, e.g. because you need this because some of your .luac files contain hand-written bytecode, be considered a fork?
