This is in System.Runtime.Loader.Tests:

It could be that we intentionally do not want to apply changes to a task-returning change until the scenario is supported, but it is an observable change, so not yet sure how to deal with this.

Could this also be due to the fact that the tool we use to generate the updates doesn't understand async v2? That tool currently lives in https://github.com/dotnet/hotreload-utils, but there's been discussion about moving it to dotnet/runtime.
