The process is open for anyone to submit proposals so nothing stops wacky ideas to end up in rfc’s. That does not mean they have a realistic chance of being accepted.

Nothing wacky was even close to being accepted.

The weirdest proposal that made it into rust was auto deref and I think that’s a question of balance. I am on the side of the advantages outweigh the disavantages and rust without auto deref would not be a sane language but maybe some other patterns would have emerged.

I think no. The stuff the op is describing is mostly not on the ergonomics agenda (I was thinking "strawman" while reading this), except for possibly limited automotic cloning for trivial types like `Rc`. It doesn't seem to describe the team's actual thinking about ergonomics. The Rust team is very aware of the importance of writing foolproof correct code in Rust (that's what it is designed for), and unless some major shift happens, I doubt they would make any major correctness sacrifices for the sake of ergonomics.
