[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?

Start by reviewing the OtelSdkBundle and Symfony instrumentation bundle references named in the issue, along with the linked read-only repository. The issue provides no implementation files, tests, or acceptance criteria; done would require an agreed roadmap and compatibility policy to be documented.
