Design meeting: `cfg_version`

[traviscross]

Summary

We have a number of questions to resolve to unblock the stabilization of cfg_version (in any form). Probably this is going to require a design meeting.

• RFC: #[cfg(accessible(..) / version(..))] rfcs#2523
• Tracking issue for RFC 2523, #[cfg(version(..))] rust#64796
• Stabilize #[cfg(version(...))] rust#141137
• Stabilize #[cfg(version(...))], take 2 rust#141766
  • Concern "let's take rust_version seriously": Stabilize #[cfg(version(...))], take 2 rust#141766 (comment)
• Decision: Use the condition name rust_version for RFC 2523 rust#142651
