I opened a PR on the SDK targeted for .NET 7 to address this. It probably wouldn’t be a high enough severity to make it into 6.0 servicing fixes, though.

Most of the other commands are implemented as actual system.commandline commands. Some, like Nuget, FSI, MSBuild, and others, forward along to other binaries shipped in the SDK. For those, we’ve customized help output to forward the help request to the underlying binary (as opposed to the default system.commandline help output that you’re seeing here generated for FSI).

To fix this we would need to replicate that same forwarding pattern. Very easy to do, just something that needs to be done in the SDK itself.
