I would like to request the following function be added to subr.el:
(defun add-several-to-list (list-var &rest elements)
"Add to LIST-VAR all ELEMENTS."
(dolist (element (reverse elements))
(add-to-list list-var element)))
This is useful in adding many items to configuration variables without
duplication, while keeping the same order, and avoiding repeated calls
to add-to-list.

I think this seems like a too specialised function to be generally
useful. And it's about the same thing as
(cl-delete-duplicates (append old new))
So I'm closing this bug report.
