I think that the \User Guide to the UNIX System/ rebutts this as well as
I could:

"In the UNIX system, files have no internal structure; they are simply
a finite sequence of arbitrary characters."

A Unix file is a series of bytes, nothing more is needed to make it a
'proper' UNIX text file.  The reason that sed and some (few) others discard
the last few bytes after the last newline is because these utilities work
on 'lines' of input -- and the definition used by all (most?) of them for
a line is zero or more non-newline characters followed by a newline.
