This is what the authors of 'The optimizing translator' at
http://as400.rochester.ibm.com/beyondtech/translator.htm
say about MI:

One of the most distinguishing features of the AS/400 computer system is the
technology-independent machine interface (MI). The MI architecture defines a
complete set of instructions to operate on data and objects, and to control a
program's flow of control. In conjunction with development of the Integrated
Language Environment (ILE), the MI architecture was extended with additional
computation and branching instructions based on W-Code, which is the compiler
intermediate language generated by the latest generation of IBM compiler
front
ends. The result of these extensions is commonly referred to as new MI (NMI).

At least in their minds, MI is one if the "most distinguishing features of
the AS/400
computer system" rather than 'just something..."
