Semantic Convention tooling group is deprecating build-tools in favor of new code-generation tool - weaver, see open-telemetry/build-tools#322 for the details.

Build-tools are compatible with the latest version of semantic-convention (1.28.0), but might become incompatible with the future versions of semantic-conventions. New features (such as event definition) are added to the weaver only and won't be supported by the build-tools.

Migration steps are documented here along with some non-normative guidelines on the code organization and artifact stability.

Looking for volunteers and happy to help or provide any additional details.
