Yes, `add-to-list' should not be used on locals:

,----[ C-h f add-to-list RET ]
| add-to-list is a compiled Lisp function in ‘subr.el’.
| (add-to-list LIST-VAR ELEMENT &optional APPEND COMPARE-FN)
| [...]
| This is handy to add some elements to configuration variables,
| but please do not abuse it in Elisp code, where you are usually
| better off using ‘push’ or ‘cl-pushnew’.
