The commands and values were not very good names to what the byte sequences actually are: opcodes and their operands. In many other places, we were already calling the byte in the Command stream as Opcode, so a logical name for a sequence of these is Opcodes. Values is such a generic name that it's not immediately clear that this sequence is related to the opcodes. Operands is not perfect but clearly suggests that this sequence is related to the Opcodes.
