I'm not really up to speed on what the Rust team is thinking, but basically no. These are not the kinds of things the Rust team would do to improve ergonomics. Correctness is forefront in Rust. The only thing I can think of like this op that has seriously been considered is automatic cloning for trivial types like `Rc`.

The Rust team thinks really hard about correctness before making any decisions and isn't going to add any ridiculous footguns to the language unless there's some organizational catastrophe that puts monkeys in charge of decision making.
