I run into crates that have issues working on nightly over, and over, _and over_ because of bad auto-detection. I would really like a way to just say \"I'm on at least the latest stable when you were published, use all those features\" and bypass any attempt at detecting for MSRV's I don't care about or unstable features _I do not want used_.",
