How do I hide these waiting logs?

Is there a non-trivial reason for why these print? Seems like a quick PR if not.

This is not a wait-on issue. It's something like webpack-dev-server not liking wait-on's pinging it while it's still finishing its build — but that's the whole point of wait-on;))

So to suppress this you'd have to look around https://github.com/webpack/webpack-dev-middleware#faq and similar that you depend on, to check if they can suppress this output.
