I think it’s safe to turn the default post type as hierarchical. The only difference is that it will have the field post_parent filled on DB, so you can correctly link one post to another with functions and accessing $post->post_parent property.
If you ever needs to go back, or if for some reason you deactivate the hierarchy property, you should not lose your post association either.
