Wrangler log filled with "Waiting for connection"

When running wrangler dev, the log shows “Waiting for connection” every few seconds.
This is really redundant and annoying.
I have to keep scrolling up long pages of text just to find the real log lines.
It makes debugging a nightmare.

Please stop printing these lines. One time at the beginning is really enough.

I also have this issue.

I only get it when using a route with a pattern and zone_id supplied. This seems to also prevent any console.log messages being output to the terminal.

If I remove the route then the messages stop and the log works as intended.
