Org implements minimal alignment rules, but it does so across all major
export back-ends. Introducing some new syntax here has at least
2 drawbacks:

  1. It requires an implementation in every major back-ends, which may
     not be always possible (e.g., in LaTeX, another default package is
     required)

  2. It may introduce some false positives (e.g., is "| <foo> |" an
     alignment cookie or a regular field?).

I think #+ATTR_BACKEND: :align ... goes a long way towards removing
these limitations, at least on the export side.
