Since Unity's trying to shit the bed with a lot of how it wants to handle web-based games, it seems like there should be some precaution for any developer that has an existing project on here, since the company's going to try to target games made before 2024 as well. I'm not suggesting something like a mass-takedown of any game made in Unity, just a single, conscious opt-in for anything out there right now that basically confirms that a dev understands the risks with uploading.
