PR #33015 introduces a profiler panel for the HttpClient component.
It was decided to merge it and improve it in nex iterations.

Here are the ideas that would be great to contribute, help wante:

• the panel UI could be improved I suppose, e.g. a tooltip on hover in the toolbar
• putting requests in the "Performance" tab would be great (all timings are already in the collected "info")
• response bodies are not collected yet [HttpClient] collect the body of responses when possible #35407
• when a transport error occurs, (ie the "error" info is populated) we should maybe have a better display too?
• add a copy-as-curl button next to each request [HttpClient][WebProfilerBundle] Add button to copy a request as a cURL command #43931
