MSP430FR2355: msp430fr2355.h defines ports that don't exist

Hello MSP430 team,

I'm using the included msp430fr2355.h header in CCSv8 and I noticed that it defines GPIO ports up to port J even though the physical GPIO ports end at port C.

Since I want to use define statements such as 

#if defined(__MSP430_HAS_PORT8_R__)

to determine certain IO mappings, these define statements in the headers really mess that up. Is there a reason for including these define statements for IO ports which don't actually appear on the device? 

Regards,

Munan
