There will be problems building with 2.69 on Ubuntus older than 12.10,
and Debians older than wheezy.

% rmadison autoconf
  autoconf |     2.61-4 |         hardy | source, all
  autoconf | 2.65-3ubuntu1 |         lucid | source, all
  autoconf | 2.67-2ubuntu1 |         natty | source, all
  autoconf | 2.68-1ubuntu1 |       oneiric | source, all
  autoconf | 2.68-1ubuntu2 |       precise | source, all
  autoconf | 2.69-1ubuntu1 |       quantal | source, all
% rmadison -u debian autoconf
 autoconf | 2.67-2 | squeeze | source, all
 autoconf | 2.69-1 | wheezy  | source, all
 autoconf | 2.69-1 | sid     | source, all

FWIW, precise is Ubuntu 12.04 LTS, so it carries Python 2.7 and 3.2.  I think
it would be fine to update the default branch (i.e. 3.4), but I'm not sure
what benefit you gain from making this change to stable branches, and you
could potentially cause build problems, which you may not find out about for a
while, e.g. when 2.7.4 is released and all the distros go to update.
