Remove flags which when enabled have no effect like Revamped Incognito, Branding UI, and others, since they have no point to be there in the 1 place if when turned on or off, they do not work.
@op2 There is no reason for them to do it. Also, flags are for the developers to enable/disable features that they are working on and for users that may like to test those features in advance.
And as I said, not all flags will result in a visible change.
