"textContent": "MusicalNinjaDad:\n\n> My worry would be `autocfg`. If anyone has probes with a leading `#[deny(warnings)]` then that could break with rather nasty consequences\n\nUnsure about T-compiler but T-cargo has decided to not support build probes, see Provide a way for build scripts to invoke rustc the way cargo would · Issue #11244 · rust-lang/cargo · GitHub\n\nWithout Cargo support, build probes have some gotchas.\n\nAlso, for fully general build probes, like `autocfg`, the edïtion should be set. The caller has to do this currently. We've approved telling build scripts the edition but it is unclear if that might get superseded by a compiler feature.",
