Could these 2 use cases be refactored?

  (mapcar #'cdr (org-babel-get-header params :var))

is not very far (but stlightly different) from

  (cadr (org-babel-get-header params :colname-names))

when there is a single association in PARAMS. Otherwise, it is up to the
user to know that there can be multiple :var keys but only
one :column-names.

IOW, aren't you after `org-babel-get-header' without the OTHER argument?
