I am wondering if there's a specific process for this: how does one get a maintainer other then just putting there name in here?
Topic on Talk:Developers/Maintainers
@KSiebert (WMF) If there is no maintainer for software deployed on Wikimedia servers, the process would likely be Code stewardship reviews. (But not sure if that answers your question - could you elaborate, maybe? Thanks!)
As an Engineering Manager I want to enable the devs in my team to focus on the work they feel most connected to and some of them mentioned to me recently that they would like to focus on projects that they often work on. So my question is more specifically: how can I help them to transition to gain more responsibility for a part of the codebase?
My quick answer would be by contributing patches to such codebases and by talking to existing maintainers of such codebases.
