Who is using this codec?

We’re trying to track down any downstream users of this codec as we’ve uncovered some issues in how this codec handles segwit that will end in breaking changes. Please let us know if you’re using this codec or know a project that is so that we can provide them due notice.

This issue asks maintainers or users to identify downstream projects using the codec so they can receive notice about breaking segwit-related changes. No source file, test, entry point, or concrete code change is named, and completion would depend on finding and contacting users.
