IIRC this is not possible. Well, possible, but there's just no code to
handle it. ;)

uri rules should work. I wouldn't worry about scaling too much, because
the number of util_rb_2tld listings is limited.
Another approach, since I understand you want to query against a local
URI DNSBL, is simply to use wildcard DNS entries. Thus, regardless of a
2tld listing and the resulting DNS lookup, it would return the same
listing for the pure TLD and a second level TLD.
