Hi Philip, Sergei I'm a bit confused about the order...
It was possible to switch on already. So, if the objective is to switch it on by default, the appropriate process flow would appear to be: - Sergei lets Philip know of the intent (since Sergei knows best when the code appears mature enough) - Philip does his testing nasties with the switch enabled, providing feedback to Sergei/bugsystem. - once all is well, the default is changed. With the flow as going below, you can have the potential nasty of having to undo the default change again if Philip finds something that cannot be quickly fixed. Plus you have to keep track of it to make sure nothing gets released before testing is completed successfully.
