I agree that it's a bad default, but changing it now is going to require
that a lot of people is going to have to change their code.

We don't have to change things not in core.

I'm for not changing defaults like this unnecessarily.  And it is
unnecessary -- things work for people now (because they've adapted to
the behaviour), and having the default be the established behaviour
wouldn't limit the usability of the feature.

But I'm going to stop arguing about this now, because we're just
restating our arguments.
