Our long-term vision is smarter backend routing. A system that identifies where a question would be best suited, whether that be adding certain tags or considering other Stack Exchange sites. In the near term, we are consolidating off-topic flags into the existing flag workflow. This reduces the number of clicks and menus you have to navigate and removing the friction and redundancy currently found in the off-topic sub-menus.
This sounds like a good idea on paper, but have you done any research into it? There's a reason why moderators decline most requests for migration. We can move any question to any other site in the network, even if it's many years old, but we don't.
The network doesn't have a dedicated site for every question. Some questions simply cannot be answered by the community. For example, many cloud questions (Azure, AWS, etc.) have been closed as off-topic, not because they belong on a different site in the network, but because they can only be answered by the cloud provider and that information is fully in their control. Answers provided by community members could be unreliable and cause the information seeker to suffer financial repercussions.
This reason has also been used for posts that cannot be categorized as anything else. Things that aren't questions or requests for knowledge. Posts that do not belong on any Q&A site. Even the most intelligent system could not route it to a place where it belongs. Sure, they could be dealt by asking the mods to delete it straight away, but it's not something that a mod needs to deal with when we have appropriate close reasons.
