The following issue lead to add a weight field to the {system} table.
http://drupal.org/node/42886


But how to use? How contrib modules can/should use the weight column in
the system table? Updating the {system} table themselves from within the
installation hook [1], the enable hook [2] ?


Is it as simple as document the feature? ...or it is also required some
kind of API to update the weight of a module?
