Ordering rich rules

[Jeff White]

Is there any way to order rich rules in firewalld on CentOS 7?  If I 
remove all rules and add them back in firewalld seems to put them in 
whatever order it feels like.

Alternatively, can I change the default policy of a firewalld zone? At 
the moment I don't see any way to have a zone accept traffic by default 
other than adding a rich rule allowing 0.0.0.0/0; and I don't see a way 
to ensure that rule is at the bottom.
