Description

It has been mentioned several times, both in meetings and other issues, to provide support for diagnostic channels, which seems to be something that wants to be integrated into Express no matter what. I am posting this in the issue in case anyone is interested in working on it.

The integration should also be done in the router module.

Research direction
The issue requests adding diagnostic channel support to Express, specifically integrated into the router module at https://github.com/pillarjs/router. Investigate existing discussions in comments and meetings for desired behavior. Potentially look at how other Node.js frameworks implement diagnostic channels and consider the integration points in the Express request/response lifecycle.
