Adding string> to Emacs proper is maybe additional 200 bytes but may
save a multiple of its size when packages start using it instead of
defining their own version each.  For example, there are already
gnus-string>, org-string>, and also org-string>=.  And there are also
quite many lambdas implementing string>, e.g., in emacs/lisp/help.el, so
the addition of string> can in fact reduce the Emacs footprint if it
gets used there.
