In the overall effort to increase the distributed ownership of testing at WMF (and especially of browser test ownership) I would like us to move the browser test failure/fixed notifications to the relevant teams' channels and remove them from the -releng channel.
The last part of the sentence is potentially contentious, but I want to keep it. I want the onus to be on the teams writing the code, not a central "we'll maintain your tests for you" person/team. A pretty efficient way of doing that is to make them see the announcements and not have us (RelEng) respond to them immediately.
The next/related step is to make browser tests voting...
