How would the change I suggest make the byte code platform dependent?
The idea is that all platforms would know how to treat lines that
begin with sharp sign as a comment.  The byte code with the comment
would run on Windows just as it does on Unix.

Much more difficult?  Are you serious?  This patch is trivial to
implement.  What is your real motivation for opposing this?  None of
the arguments you present make much sense to me.
