I can add an iptables rule that references an ipset of the wrong address
family, which doesn't seem sensible.

For example:

ipset create foo hash:ip family inet
ip6tables -A foo_chain -m set --match-set foo -j LOG

or
ipset create foo6 hash:ip family inet6
iptables -A foo_chain -m set --match-set foo6 -j LOG

or even more bizarrely:
ipset create foo hash:ip family inet
ipset add foo 1.2.3.4
ip6tables -A foo_chain -s 2001:35:1:2:3:4:5:6 -m set --match-set foo -j LOG
