Yup, sorry about this.

I didn't configure the wiki exactly as I had intended, which indeed had the effect that new users who've never edited before will get the visual editor on first edit (unless their machine is incompatible). The plan was to make that part of change subsequently to the main change, which was to provide only one edit tab (with the editor chosen by the user) instead of having two.

Now that both these changes are deployed, I think going back and then forward would cause confusion and disruption with no benefits for our editors. The benefit for users following the plan would have been a lack of unexpected changes. However, this is not something I can create from the spilt milk we now have, sadly.

Consequently, I won't be undoing this change, as I don't think there is overall value in so doing. In future I'll take more care in writing these kinds of changes, sorry.
