I find them glaring when browsing rustc docs, so I wonder if there is a way to remove (or toggle) them, short of removing the code block enabling them (librustdoc/html/render.rs).
No. The whole goal is to inform on the state of your code block.
@GuillaumeGomez they mean https://doc.rust-lang.org/nightly/nightly-rustc/rustc/
everything in all of the nightly-rustc crates is 100% unstable
hm I wonder if we can just not pass the -Z flag that makes everything unstable when documenting crates
