That would have no effect on node editing permissions.  However, if that
field was supplied by a contrib module, that one could alter a node's access
permission via node_access.  There are already some modules that could be
enhanced to provide this feature:

http://drupal.org/project/edit_authoring_info
http://drupal.org/project/annotate

...probably more.
