Yeah, it's really hard to strike the right balance here, and we're constantly learning from experience. Sorry for the pain! I'll put a note on the core team agenda to undergo a round of public discussion around policies here, which is overdue at this point.

Maybe a different way to frame it is: Rust provides a stability guarantee for `rustc`, but you could just as easily prioritize stability for the Rust ecosystem. If Rust gets some neat new features that break crates, the experience of stability for users is still missing.

Feel free to factor in that approximately five people use crates that I write, and most of them have bigger problems than Rust breakage. :)
