We intentionally prioritise the basic editor over VE when it's the secondary editor (shown as the second) – the description of this bug is already met for e.g. frwiki. We could change this over to "make VisualEditor primary on the English Wikipedia for people for whom it's enabled", perhaps?
Sorry to clarify, for users who have made the decision for themselves OR for users that we've made the decision that visualeditor is the default editor, in the cases where one tab is visible that tab should be "edit" -> Visualeditor. Does that make it clearer?
In the weekly triage on 2015-04-22, this task was discussed. We decided not to make this change right now, as we worried that changing the site like this just ahead of, or in the middle of, deployment would be confusing and noisy and that the value-add wasn't high enough, and so we will do this later, after the quarter.
