Do those features actually cause difficulty for anyone other than compiler engineers, compared to not having them? I haven't personally seen, e.g., newbies stumbling over them; they're actually designed remarkably well to fade into the background and Just Work (i.e., you don't notice they're there, but you definitely would notice if they went away). Yes, there's something to be said for minimalism in language design, but Rust without those features still isn't very minimalistic, so dropping them would seem to bring about most of the costs of minimalism without the benefits.

I haven't personally seen, e.g., newbies stumbling over them; Pretty much all of the features in the list are things that either I have struggled with when learning Rust (the Copy trait and lifetime elision), or I've seen beginner struggle understanding (both new hires, or students at the place when I gave Rust lectures).
