It came pretty close to happening in Rust 2024, but it was determined that there just wasn't enough time left before the end-of-year deadline to roll out such a big change.

When the new edition rolls around that swaps to the new type, I expect a bunch of libraries are going to get really annoying to use. And vice-versa for new libraries with the old editions.

The full transition won't be completed until 2027 edition, when the meaning of the `..` operator is expected to swap to the new type.

i came here to comment the same! could not be happier!
