As an employee of a company that makes a DNS management product, I can say that there is a strong temptation to think this way when designing such a product. We have mostly managed to avoid this type of stupidity, but I still get tripped up by it occasionally. When I find it, it gets logged as a bug report, of course, because we have plenty of customers who rely on "dotted records".
