Why not use original rbs2-corr-id for trace-state/parent-id

Instead of using another custom header.

Mainly backwardscompatibility. You never know what might depend on something, so in case messages are being based to/from services that doesn't have open telemetry enabled, we are not going to conflict with any custom logic. Though the question is still valid.

@mookid8000 Would there be anything wrong with co-opting the mentioned header for this?

@zlepper I have no idea, actually. 🙂
