As explained, this is not realistic.

The manual is, IMO,  pretty explicit:

     Finally, a =E2=80=98COMMENT=E2=80=99 keyword at the beginning of an en=
try, but after
  any other keyword or priority cookie, comments out the entire subtree.
  In this case, the subtree is not exported and no code block within it is
  executed either.  The command below helps changing the comment status of
  a headline.

I don't think there is any. This is basically what my first patch did
(i.e., removing any COMMENT subtree at the very beginning of export
process), but it nevertheless surprised some users.
