Why it is allowed for developers to overrule community consensus? If German Wikisource has the opinion that IPs should be allowed to change the proofread status in the "PR2" system then this should be made possible.

I cannot see any Wikimedia Foundation rule that accepts serious changes by developers without reaching consensus in the relevant community.
