Hmm... I'm a big fan of a lot of the things that the tokio project has built and a happy user of axum.
I'm not sure that projects like Topcoat and something like their ORM is a great direction for the project, and worry that they will possibly gain outsized adoption in the community based on name recognition rather than merit.
I think it is highly likely topcoat / toasty will get split out. It is just work, especially since tokio-rs has more CI usage available than the default GitHub org.
