I guess the core of my argument is that none of these features need to be used. It's very easy to write basic scripts in Rust at least in my experience. Maybe you might encounter difficulty with the borrow checker occasionally, once in a blue moon now that non lexical lifetimes are a thing. Most of the other disadvantages also apply to Swift.

Either way, people will find a way to justify their preference. The people in question liked Swift, and there's nothing wrong with that.
