Hello,
The commit message in this commit is golden:
http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=3ac619c8ac9934a2a1368f3de8ffad951f900067
Using that info, I came up with a "classified" version of n macro for
markdown/HTML:
#+MACRO: sec (eval (concat "<span class=\"section-num\">" (number-to-string
(org-macro--counter-increment $1 $2)) "</span>"))
Based on that I have two questions:
1. Can you please document the use of eval form in Org macro definitions in
the Org manual(.org)? Its awesome wasn't evident to me until I read that
commit message.
2. (Another question on canonical approach) What would be the recommended
approach for an exporter backend to add new macros or override existing
macros (like "n" macro to wrap the string with HTML class as an example)?
Should it update org-macro-templates in org-export-before-processing-hook?
or something similar?

I guess it isn’t documented in the manual...
I agree, there could be a second example and the mention of using lisp or
at least a mention of the ‘org-export-global-macros’ docstring.

Do you really need to overwrite an old macro? Couldn’t you define a new
macro? org-export-before-processing-hook is definitely the right hook,
cf. ‘org-export-as’.
(defun fooreplace (backend)
(when (eq backend 'mybackend)
(goto-char (point-min))
(while (search-forward-regexp "{{{foo\\((?\\)" nil t)
(replace-match "{{{myfoo\\1"))
(goto-char (point-max))
(insert "\n#+macro: myfoo mybar\n"))))

Or,
#+MACRO: sec @@html:<span class="section-num">@@{{{n($1,$2)}}}@@html:</span>@@
