Or maybe programmers use these database systems because they work,
and work good enough?

In other words this means, that John Doe will have more headache with
such system, which will be pretty compelling reason to stick with
RDBMs which "just work".
In short - I don't share your vision of the bright future of XML DBMS.
Time will show.
