Given that we compile with nightly on CI and given that we fail on warnings, isn't that good enough? What bug in the past would have been prevented if we were to run nightly locally? |
No particular bug. Rocket recommends the same thing for better macro diagnostics for example. Just wanted to help users in not having a different setup than in Ci! |

Description
Using nightly Rust for local development is regarded as useful because it helps detecting compiler bugs early and tends to provide better diagnostics.
Related: #4575.
Notes & open questions
I am not sure we want to go as far as actually recommending this. Happy to leave this PR open for a bit and experiment ourselves first, how good using nightly Rust for local dev is.
