Hello,

It seems that Traefik Hub provides a way to include a `trace_id` in response headers, which is very useful for diagnostics.

Is there an equivalent feature available in Traefik OSS?

I came across a [similar question](https://community.traefik.io/t/return-the-traceid-as-part-of-the-response/2123) regarding Traefik v2, but it didn’t receive any answer, so I’m not sure about the current state of this capability within v3.

If this is not supported out of the box, would it be possible to implement it via a Traefik plugin? More specifically, can a plugin access the trace context in order to extract and inject the `trace_id` into response headers?

Thanks in advance for your help.
