Jeez Louise, Magnus: WHEN are you going to turn on the validation feature? Are you waiting for Anthere or someone to "certify" that there is a "consensus" to try out the feature? Please just turn it on. We will all play with it for a few weeks and decide if it should be permanent. And if there's a "performance degradation", surely you will detect that problem and yank the feature. But you already assured us that this is highly unlikely.
