I don't agree. If you want something to be open, you should have to
declare it so. But I don't much care about the default, as I'm going
to turn the knob to "closed" on my schemas explicitly no matter what
the default is.

That's because the notion of validity almost disappears, IMHO.

I don't want openness, so I don't see the problem :-)
