Description

Describe the feature you'd like supported

Just support for stream-level ToS/TC for more precise prioritization of network traffic

Proposed solution

There will be no need to be afraid that some vital messages will not reach the consumer. And simplification of this mechanism, because now it is possible only within the framework of different connections

Additional context

No response
