I've been pinging for reviews on [1] for a while now. :/
I'm just doing what you do in patches 9-10 in one go, and I very much
prefer having the [CONNECTOR:%d:%s] bit as the first thing in the
debug. For an individual line your style might read better, but for
reading a log with a bunch of consecutive lines, I think having it as a
prefix reads better.
BR,
Jani.
