Any plans for Smithy 2.0?

Are there any plans to support [Smithy 2.0](https://aws.amazon.com/blogs/developer/introducing-smithy-idl-2-0/) ?

We use smithy internally for specifying APIs and interfaces, rust-atelier for parsing, and code generators to build for a few target languages. It would help our planning to know whether there are plans to support Smithy 2.0 parser and/or AST with rust-atelier.

Thanks!
