request_id_extension and X-Request-Id modification

[Alex]

For now envoyproxy modifies X-Request-Id values with tracing sampling decision (more info in documentation: https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/filter/network/http_connection_manager/v2/http_connection_manager.proto.html?highlight=tracing#envoy-api-msg-config-filter-network-http-connection-manager-v2-requestidextension).

The configuration of the request ID extension. This includes operations such as generation, validation, and associated tracing operations.


If not set, Envoy uses the default UUID-based behavior:


Request ID is propagated using x-request-id header.


Request ID is a universally unique identifier (UUID).


Tracing decision (sampled, forced, etc) is set in 14th byte of the UUID.

Is it possible to turn off this logic and keep X-Request-Id value same?

I found this issue: https://github.com/envoyproxy/envoy/issues/9076 But as I understand the solution, I have to build envoy with my implementation of RequestIDUtils interface (extension). Can I just monkey patch it so it won't do anything with request-id header?
