The implementations are a way to optimise the functions -- they provide
no (well, little) information needed to use the functions. So I'd argue
that they aren't needed by users.
That is, whether seq-map is optimised by doing
(defun seq-map (function sequence)
(if (eq (type-of sequence) 'list)
(seq-map-list ...)
(seq-map-general ...)))
or whether that's achieved by defgeneric is immaterial to people using
seq-map: The interface to use remains identical.

There's two:
(cl-defgeneric seq-map (function sequence)
(cl-defmethod seq-map (function (sequence sequence))
