I think the word 'uninformed' here is key -- after all, the entire concept of the font being discussed is an experiment (of the 'what would happen if we look in this gap in this classification system?' kind). But it's not an uninformed experiment, it's one that arises from knowledge of what's been done historically, which is why it's interesting. Uninformed experimentation would be more likely to just reinvent some previous idea, badly. (Not that recapitulating previous work is inherently bad; but the idea of an informed experiment would be to recapitulate some development knowing that that was what you were doing.)
