Because it is not theoretically possible, given the limitations of

simply no way to get the information (file size, or EOF) from one
system to the other and preserve the trivial unstructured

That's what protocols like XMODEM etc do; create an information
structure with which to send meta data.
Well, my guess
would be that it has no way to determine the EOF coming
over the line, as it can't just "check the file length", unless
there's
a ^Z there to indicate it. Thus, ASCII mode is needed.
And the programmers were not smart enough to figure a way around this
because...why?
