Right; this is what the bug report claims makes latexmk and biber stop
working, but you say later that this isn't the case?  Could there be
versions of these programs that choke on brace-less entries?

(If it sounds like it's been a long time since I've used bibtex and has
forgotten most everything about it, that's correct. :-) I've now Cc'd
the bibtex maintainer.)

Yes, the manual just refers to the doc string:

---
Bib@TeX{} mode is a major mode for Bib@TeX{} files, which are commonly
used for keeping bibliographic references for @LaTeX{} documents.  For
more information, see the documentation string for the command
@code{bibtex-mode}.

Right.
