I'm not sure I follow.

Can you name another language where printing a string
to standard out will print the delimiters used to
create a string literal?  I cannot.  This is at least
unexpected, and I suspect is should be considered a bug.
Can you make an argument that a user should expect InputForm
rather than DisplayForm when printing to standard out
(i.e., when using the -script option)?

Btw, you cannot just convert to DisplayForm to Print the string;
that does not work at the console.  In short, the behavior of
Print is quite odd, unexpected, and I claim buggy when running
with the -script option.  (But I'm new to Mathematica and willing to
listen to reasons for this surprising behavior.)

Related: I do not understand why one must use ToString
on a StringForm when printing it in a console script.  The
behavior in a notebook is what is expected, and imo it should
be what one sees at the console.

If I understand correctly, the -script option is new, and it looks
like not enough of the Mathematica output behavior has been adjusted to
this flag.
