Thanks for the suggestion, although my understanding is that if the form
is not evaluated the quote should not make a difference.

With this in .dir-locals.el:

((nil
  . ((warning-suppress-log-types
      . ((missing-lexbind-cookie))))))

or this

((nil
  . ((warning-suppress-log-types
      . (missing-lexbind-cookie)))))


emacs -Q

M-x load-library path/to/file.el

the *Warnings* buffer stills pops up with the lexical-binding cookie
warning.

There is no indication that .dir-locals.el is taken into account when
the file is loaded. I put some junk on .dir-locals.el and make no effect
while loading the file, but visiting it showed this message:

Invalid data in /home/oscar/elisp/singles/.dir-locals.el: oarnst
