Yes, now people who want what the OP wanted should be able to have
that easily.  But I would hesitate making that the default, instead
leaving it to user customizations.  We could have a minor mode to do
that, though, so that users who want this won't need to customize
individually each character's category set.

Of course, the harder part here is to decide which of the Zs
characters will allow word-wrap on them.  I don't think all of them
should.
