Yes, it looks like this makes the cl-letf case fail:

(ert-deftest cl-lib-symbol-macrolet-hide ()
  ;; bug#26325, bug#26073
  (should (equal (let ((y 5))
                   (cl-symbol-macrolet ((x y))
                     (list x
                           (let ((x 6)) (list x y))
                           (cl-letf ((x 6)) (list x y))
                           (apply (lambda (x) (+ x 1)) (list 8)))))
                 '(5 (6 5) (6 6) 9))))

It now returns (6 5).  But...  I'm not actually sure what the semantics
with cl-symbol-macrolet + cl-letf are supposed to be, really.
