Doesn't look wrong to me.  But if we use it we'd have to change the
comment below:

;; Values :save and :restore are not used in this package, because usually if
;; you don't want to save a parameter, you don't want to restore it either.
;; But they can be useful, for example, if you already have a saved frameset
;; created with some intent, and want to reuse it for a different objective
;; where the expected parameter list has different requirements.
