I don't think this is practical, especially for what I do. The websites I build are intended to generate new business for my clients. We don't support IE6 but we do support IE7-8 because, between them, they are the most commonly used browsers to our sites (supported by stats) and turning those people away would lead to a massive loss in potential business. Perhaps your web apps and websites are targeted at the type of people who always stay up to date with their browsers bug I can't see that being the case at all for what I build based on the data we've collected.
