mx/defn and malli.destructure/parse unexpected handling of seqexps

If I write

(require '[malli.experimental :as mx])
(require '[malli.core :as m])

(mx/defn ^:malli/always f [xs :- [:* :int]]
  (malli.core/validate [:* :int] xs))

(f 1)
;; => false

(f [1])
;; => Execution error (ExceptionInfo) at malli.core/-exception (core.cljc:136).
;;    :malli.core/invalid-input

(m/validate [:* :int] [1])
;; => true

I would expect (f 1) to throw an except and (f [1]) to return true.

I think this is because the schemas for the arguments are combined using [:cat ...] and [:cat [:* :int]] 'flattens' the expression, so [[1]] is not valid for [:cat [:* :int]]. In this simple case the args schema should be something like [:tuple [:* :int]] for which [[1]] is valid.

Of course this is not so simple for varargs.
