&allow-other-keys is always true for the pcase version.  As I understand
what &rest does, it lets you bind certain keys, and then bind the map
minus those keys to another variable.  Thereʼs nothing like that out of
the box, but it can easily be implemented:

(pcase-defmacro map-and-rest (rest-var &rest keys)
  `(and (map ,@keys)
        (app (map-filter (lambda (key _val) (not (memq key ',keys)))) 

(pcase-let* (((map-and-rest rest foo bar) '((foo . 1) (bar . 2) (baz . 3))))
  (list foo bar rest))
;; -> (1 2 ((baz . 3)))
