Yes, I know about this, thanks all the same, but in a huge database, which this one isn't, imaging the result of materiali[zs]ing all those empty tables again. The point of the deferred segment creation is to save space - which it does, admirably - seems a shame to have to undo all that good work when we need to downgrade/migrate it to a Standard Edition database.
