How?  You know, when many, many, many keywords or options changed
between Org 7.9 and Org 8.0, there was nothing to support backward
compatibility: much too complex, I guess.

As a reminder, some of the changes:

  #+STYLE: ...                             ->  #+HTML_HEAD: ...
  #+BEAMER_HEADER_EXTRA: \usetheme{Madrid} ->  #+BEAMER_THEME: Madrid
  #+ATTR_LaTeX: width=1.1cm                ->  #+ATTR_LaTeX: :width 1.1cm
  #+ATTR_LaTeX: align=lrrrr                ->  #+ATTR_LaTeX: :align lrrrr

Add a variable "org-support-old-macro-syntax" seems overkill to me. But,
yes, I know, that's something that will have to be clearly mentioned in
the NEWS as something that did change, and as some consequences.

Best regards,
  Seb
