The motivation was almost certainly compatibility UNIX shebang lines for shell scripts:

    #!/usr/bin/dotnet run
    Console.WriteLine("Hello from a C# script!");

Which just looks like a crime against nature and right order of things.

It's really hard to explain to anyone who wasn't born in a monoculture, but I come from an eastern european country where in my childhood there may have been maybe a few hundred truly foreign people living there at any one time, mostly diplomats and their families. Decades later I visited and saw a chinese immigrant speaking my native tongue. You can't imagine how... disconcerting that is. Not bad, I'm not against it, it's just... weird.

This feels exactly like that.
