For example, daily browser tests for the AdvancedSearch extension should include a maintainer email so that breakage is handled by the right group. Here are some possibilities:

• fundraising-tech@wikimedia.de: This was the maintainer at one point, but I think that team has moved on.
• techwish-devs@wikimedia.de: This seems to be the current team that might be responsible?
• maintainers@wikimedia.de: No such address exists yet, but maybe we should consider this pattern so that we're future-proof and regardless of team structure, someone is assigned to read this inbox and forward.
