The variable could be more general, e.g.,
org-html-export-equation-reference-format, and default to "\\ref{%s}".
Note the export back-ends do not use variables directly. It would be
(format (plist-get info :html-equation-reference-format)
(org-export-get-reference destination info))
where the correspondence between :html-equation-reference-format is set
in back-end definition.
Also, it needs to be referenced in "HTML specific properties" section of
the manual.
Would you want to propose a patch ?
