Hide "Revision information" field when first creating a session

The "revision information" field may be confusing to first time Drupal users, adds clutter to the session submission form, and seems unnecessary for the first revision of the node.

We can
a) Remove it from the session form if a user does not have administer nodes permission
b) Same as above, but only on the initial submission
c) Make this a simple contributed module that allows users to configure a and b for any content type.

Thoughts?
