You are allowing people to write ugly code to gain some efficiency,
without loosing portably.

But there is already a language for this: C. ANSI/ISO C is portable and
allows you to write very efficient string processing code.

Please don't destroy the nice language Scheme with such provisions for
ugly code as allowing string indexes in every string procedure.
