Hi we have only had good experiences with RTC in log4net. Of course, a lot depends on a review being done in a timely manner. The feedback is always valuable and I can apply the changes before merging to main. But most of the time, a pending review does not stop me from continuing my work. Either I append my changes to the existing branch (when related) or I create a new branch, based on the existing one and create the pull request after the first one was merged.
So it's a +1 from me. Regards. Jan
