I see [RFC: The ConstDefault trait](https://github.com/rust-lang/rfcs/pull/2204) was closed in favor of [RFC: const bounds and methods](https://github.com/rust-lang/rfcs/pull/2237), which was closed also.

I frequently need const initializers, so I wondered about why we don't have `ConstDefault` already.

Is this still on the radar?

Yes, people are working on a solution to this: [https://github.com/rust-lang/rust/issues/67792](https://github.com/rust-lang/rust/issues/67792)
