This would be immensely useful for debugging purposes

Could you explain which messages you are currently missing with the DEBUG=pw:browser today?

[Andarist]

We are configuring Playwright to use our fork of Chromium at https://www.replay.io/ . At times, it's helpful for us to debug things happening there using its verbose stdout/stderr output. We can pass the required RECORD_REPLAY_VERBOSE env variable to it using launchOptions but we still miss the logs because the browser's output is not observable without this added debug call

I.e. if you run DEBUG=pw:browser npx playwright test, what kind of output does not end up printed?

Let's follow the process and file an issue so that we could triage it!
