I mean, you're right that this is a problem and it gives people the ability to shoot themselvesin the foot but bytes and byte order is apart of a C programmers framework for better or worse. I want to argue it gives you incredible control of the data at the lowest level and that's the tradeoff. If you write non portable code, it seems like you have to go out of your way not using standard portability types. If you define your own struct types I can see where this goes awray, but I think " __attribute__((__packed__))" eliminates alignment spaces for that case.

BUT, if you are coming from a networking/file perspective I can emphathize with you. Byte ordering is a pain for data serialization, even that has chance to cause issues and is no doubt a source of bug and pain.
