After poking around in the bibtex code, I think this just isn't
supported.  All the variables are like this:

(defvar bibtex-entry-maybe-empty-head nil
  "Regexp matching the header line of a BibTeX entry (possibly without key).
Initialized by `bibtex-set-dialect'.")

And the dialect won't be set until you load a file, so I don't think
this is a bug.
