[opentelemetry-php-contrib] OtelSdkBundle roadmap questions

Hi, I'd like to use OtelSdkBundle to start adopting opentelemetry. Currently there is abandoned package open-telemetry/contrib-sdk-bundle which suggests using open-telemetry/symfony-sdk-bundle.
This package directs to a read-only repository containing two bundles:

• open-telemetry/contrib-sdk-bundle
• open-telemetry/contrib-symfony-instrumentation-bundle

The first one open-telemetry/contrib-sdk-bundle in its readme mentions the uprising Instrumentation bundle (I guess the second one) which will add instrumentation for symfony project.

I have a few questions:

1. Is there any timeline for a stable release? When we can expect to see version 1.0.0?
2. What is the scope for the stable version for open-telemetry/contrib-sdk-bundle?
3. Is there any publicly available roadmap where we can track development progress?
4. What is the scope for the stable version of open-telemetry/contrib-symfony-instrumentation-bundle?
5. In terms of backward compatibility: should we expect any breaking changes before version 1.0.0? I know that semantic versioning allows breaking changes before stable release but I'm asking about Your plans/policy. Do You have a large refactor in mind that could lead to breaking change in the public API?
