Some people might be worried that, if it's a bad change, it won't be reverted because nobody will be able to read their complaints.
This is one of the few cases where the worse a change is, the less of a voice you will have after it happens. I'm not saying it will be bad, but you can see why that would be frightening.
The "karma elite" will be able to read their complaints. Usefully, the people with the ability to revert the change are a strict subset of the karma elite.
Is there any information on how spread out geographically the "karma elite" is. If it's very US centric then users in other time zones may suffer most in terms of pending delays.
