So, no "useful" programs were written prior to 1990? That's news to me...

No. I can, and should, take care of binary layout at the point I need to
[de]serialize data that is going to exist elsewhere, whether that is on
disk, or across a network. However, for internal operation, I just need
some representation that is "good enough". (See also Jake's reply.)

I think every programmer that deals with embedded systems is liable to
disagree with you.

Moreover, I can trivially give a counterexample: the existence of
int_leastN_t, int_fastN_t, etc.
