Evaluate the following

(progn
   (defvar my-var :default-value)
   (make-variable-buffer-local 'my-var)
   (let ((my-var :let-value))
     (setq-local my-var :buffer-local-new))
   my-var)
=> :default-value

(progn
   (defvar my-var1 :default-value)
   (make-variable-buffer-local 'my-var1)
   (setq my-var1 :buffer-local)
   (let ((my-var1 :let-value))
     (setq-local my-var1 :buffer-local-new))
   my-var1)
=> :buffer-local

In both cases, setq-local has no effect.

(I stumbled over this because lexical-binding is set to nil in *scratch*
when using persistent-scratch (MELPA).  It's quite convolutetd, but in
short: Custom loads persistent-scratch, which loads the contents of
*scratch*, and calls lisp-interaction-mode.  Lisp-interaction-mode
setq-local's lexical-binding to t, but this doesn't work because all
this happens during an eval-buffer that has a specbind of
lexical-binding to nil.)
