Hi, I just noticed that test2wiki is in group1, while I think it should be in group0, as other testwikis. That means some bugs can't be tested at all in any group0 wiki, for instance, bugs that affect wgAddGroups loading (T273296 is a very recent instance of such bug), which primarily affects FlaggedRevs wikis, and also other wikis that add groups that can be granted by sysops/bureaucrats.
Why is test2wiki in group1? Shouldn't it be in group0 instead?
