True - though I don't think it would be possible for another hub to take
over instantly, as it would need to keep trying to bind to the port at
regular intervals in order to detect the loss of a hub.

There shouldn't be.

This is a valid point.
It would mean that apps that migrated to V3 would continue to behave like
they do now (i.e. with no hub) unless the developer specifically enabled
it.

Probably better for developers to evaluate whether to enable the built-in
hub in their app before enabling it, so I'll go with setting the default to
False, unless anyone has any strong objections.
