ELPA's seq currently only consists of the following
--8<---------------cut here---------------start------------->8---
(if (version< emacs-version "25")
(require 'seq-24)
(require 'seq-25))
--8<---------------cut here---------------end--------------->8---
where seq-24.el is a compatibility version, while seq-25.el appears to
be the same as lisp/emacs-lisp/seq.el (or at least the version from a
year ago). What I guess this means is that lisp/emacs-lisp/seq.el
should preserve compatibility up until Emacs 25, unless another
backport version should be added to the ELPA package.
Out of curiosity, what are you looking to change that might break older
versions of Emacs?
