It is real now, the TurboWarp developers already gave a warning that this would happen soon, and it did (on 10 November, 2022) This should have happened a long time ago; the fact that this was possible at all was a huge vulnerability in the site. It is not a great idea to let anyone see censored, deleted, or private projects with the project ID, as it defeats the purpose of those projects being hidden in the first place (and breaks moderation) If you are concerned about not being able to share projects in an "unlisted" manner similar to other platforms: you can directly distribute the sb3 file of your project to others who need to see it.
