Drupal wish: Configuration setting to make all content types default to create new revision

Update: All this is superseded by an existing module, http://drupal.org/project/content_type_overview

Requests for this feature go all the way back to the days of Drupal 4.6, at the least:

create new revision by default
http://drupal.org/node/53149
(4.6 era post!)

This feature remains wanted-- here is the manual instructions, for Stanford.edu!

Enable revisions by default for all content types
http://drupaltraining.stanford.edu/node/31

The project to do this has been started:
http://drupal.org/project/all

"This module seeks to put scattered configurations all in one place, make it easy to set all defaults at once, and (where needed) assist all core and contributed modules it touches with their configuration-in-code integration.
Motivation: Many core and contributed modules could be more conveniently administered if their configuration options were all accessible in one place. For instance, one is very likely to want to change the Create new revision setting for all content types at once. All such settings that are spread across content type forms would, not exclusively but for certain purposes, be much more conveniently administered centrally."
