Thanks for the comment. I see that "endian" is used as an adjective. However, it seems used widely, e.g. the system header file `endian.h`. There are other cases a phrase that is not noun is used as variable names, e.g. `old`/`previous`/`next`, or `Is64Bits`. Do I have any chance to get the shorter `Endian` instead of `Endianness`? :)

There are quite a few uses of `TargetEndianness`. While my long term goal is indeed to remove them, I plan to keep it here so that potential users will more time for migration.
