How come we no longer need this override? If you're relying on picking it up by
default, might that change? Seems better to make it explicit.

Yes. It relies on the default being null. I don't know how that would change
because I can't think of what it could change to. I suspect there are many
WidgetDelegates that rely on the default being null, but if we did for some
reason change that we'd probably want that new default to apply to them all,
including this one.
