CCK content type table naming

When a content type is renamed, database references to it don't change. So if I rename a content type to something more descriptive than before, it is not reflected in the database. This is an annoyance because of url paths that show e.g. on the node/add pages, because they confuse users as well as me :)
It should be either of the following:
--behavior like flexinode in this respect, that is, flexinode-1, flexinode-2, etc.
--update database entries when a content type is renamed
