Only one of the naming schemes in our paper (method C) requires that genus names not be available as clade names; see column 7 in Table 3 of that paper. On a different subject, I will take this opportunity to say that I agree with Kevin that apomorphy-based definitions should remain available for those who wish to use them. So in David Baum's poll, count me as "Pro." I also agree with Gerry's point that, because genus names frequently are based on diagnostic (and thus often apomorphic) characters, it is not reasonable to recommend that all converted names that refer to apomorphies have apomorphy-based definitions. Summing up, I feel that all three kinds of definitions should be available for use. Thus, I disagree both with those who would like to eliminate apomorphy-based definitions and with Jonathan's proposed recommendation 11.8C, which discourages the use of stem-based and node-based definitions of particular kinds of names.
