Well - truth is there is not much work done any more. Shorewall is
slowly getting obsolete because it is based on iptables/ip6tables.
Here is one contributed script to handle updating ipsets.

https://shorewall.org/pub/shorewall/contrib/DNSLookup/

At my daytime job, we created completely nftables based new firewall
which can handle dns with nftables by doing automatic dns resolving.
Idea for this came from DNSLookup and another similar scripting system
updating ipsets based on dns. But unlike with ipsets you don't have
issues with startup failing if ipset is missing which was one issue
we found with ipset based solution.

That's not shorewall but created by guys who used shorewall for 20
years.
