The x variants were an early attempt to simplify identifying processors
where part number variation did not affect the compiler, at a time when
the MSP430 product line was quite limited.  Introduction of additional
processor families broke those assumptions, particularly in the need to
vary the addresses and presence of different peripherals.

In 2013 when I last updated msp430mcu (may not have been released) there
were north of 450 distinct chip IDs that affected code generation or
peripheral address.  The generic ID originally spelled msp430x16x
covered six of them.
