Should it be done in dev mode only ?

[brunobat]

@wottop Are you thinking on continuing the work on this issue? Some considerations:

1. The response header should not be inserted by default. A new property is needed with default value to false.
2. This needs to be developed for quarkus-rest quarkus-resteasy-classic and vertx routes.
3. We need tests.

@brunobat What should we do here?

[brunobat]

Like it is, we cannot accept the PR and because @wottop hasn't addressed the comments I'm closing the PR. We can re-open it if we hear any news.

I tried that code in one of my projects. Unfortunately it also won't address resources retiring Multi responses (see also #44898). So I guess there is some alternative implementation needed to fully support setting the traceresponse.
