Thanks! This is definitely better, though still not clear in terms of the interaction between the active toolchain and package.rust-version. Maybe it doesn't need to be explained at all? However, if you look like group and lint level, they do have some excellent documentation even those are pretty well-known concepts.

BTW, I personally feel it is now unfortunately verbose 😞

Do you have an alternative?

What I'm trying to address by having this listed in the first place is for when someone asks the question "why is a lint not showing up?".

We already use MSRV in other places in the docs.

I'm not quite seeing a good place to give a more verbose explanation like rustc's.

You meant something like "MSRV: Requires 1.64+"? I think that may be the source of confusion, because some of them are active toolchain IIRC. And this one is configured MSRV.

That said, I have only a worse alternative: have a footnote on every "Minimal package.rust-version" / "MSRV" and explain what that is.

I am actually fine with the current one. Let's merge it first then.
