Custom Post Type – Title Only

I found these pages that provide instructions and examples for creating custom post types:

https://codex.wordpress.org/Post_Types

http://web-profile.com.ua/wordpress/docs/custom-post-types/

The goal is to create a post type that only provides a title field. First of all, is this possible? If so, am I correct in thinking that I would only include ‘title’ in the ‘supports’ array? Would there be any issues having a content type that only has the title field?
